Microchip Technology

The HV53001 device is an integrated driver solution for various applications, which consists of three main functional blocks (1) High voltage driver, (2) SPI interface and (3) DC/DC boost controller with power MOSFET. The high voltage driver block includes 16 push-pull drivers capable of ±135V output swing with Return-To-Zero (RTZ) function. Each output driver is capable of sourcing and sinking at least 24mA. Each high voltage output is capable of driving up to 250 pF capacitive load. A global current sensor function is also integrated into this device to monitor the charge and discharge currents. The measured current is mapped to a low voltage analog output with a scale factor of 3.1 V/V via a current sensing resistor. The SPI interface is used to communicate between the host processor and the high voltage drivers. This interface accepts a 3.3V logic I/O signal up to clock speed of 32MHz. Five digital LATCH control signals manage the data flow and the firing pattern. It establishes the output to one of four possible states: VPP, VNN, 0V or high impedance. This IC also includes an integrated DC/DC controller with power MOSFET. The controller is used in a flyback configuration to generate four high voltage rails, ±135V and ±123V for the high voltage driver block. The ±123V rails are created from two 12V floating supplies referenced to the ±135V supply rails. The converter accepts input voltage from a single 2.7V-5.5V input voltage rail. A built-in positive charge pump and a simple external negative charge pump convert the input supply to +6.5V and -6.0V supplies to power the high voltage driver block. A proper power on and off sequence is critical to ensure the operation of the high voltage driver. A power sequence control circuit is included for the user to control the power supplies to power up or down the high voltage driver. It is used in conjunction with the external high voltage FET transistors. Few safety features are added to the DC/DC converter. The over-voltage protection monitors both high voltage rails to protect the driver against over-voltage condition. A short circuit protection detects any short circuit event at the high voltage rails by monitoring the current flow through the power FET transistor. When a short circuit is detected, the DC/DC controller will shut down the converter and send a fault signal at the SHORT pin. A over-temperature monitor function is also added in the converter IC. It sends a fault signal at the TEMP pin when it detects the temperature over the threshold temperature. The HV53001 device is packaged in a 9x9mm 105 balls TFBGA package. All high voltage I/O are arranged to have sufficient clearance for safety. **Microchip has partnered with Tanvas to create this chipset that optimizes size and features for enabling surface haptic applications.**[**Learn more >>**](https://www.microchip.com/en-us/products/interface-and-connectivity/dc-dc-high-voltage-interface-drivers-amplifiers-arrays/mems-piezoelectric-drive/haptics/thin-film-actuator)

Each output driver is capable of sourcing and sinking at least 24 mA. Each high-voltage output is capable of driving up to 250 pF capacitive load. A global current sensor function is also integrated into this device to monitor the charge and discharge currents. The measured current is mapped to a low voltage analog output with a scale factor of 3.1 V/V via a current sensing resistor.

The HV5308B is a low voltage serial to high voltage parallel converter with push-pull outputs. This device has been designed for use as a driver for AC-electroluminescent displays. It can also be used in any application requiring multiple output high voltage current sourcing and sinking capabilities, such as driving plasma panels, vacuum fluorescent, or large matrix LCD displays. The HV5308B consists of a 32-bit shift register, 32 latches, and control logic to enable outputs. Q1 is connected to the first stage of the shift register through the Output Enable logic. Data is shifted through the shift register on the low to high transition of the clock. When viewed from the top of the package, the HV5308B shifts in the clockwise direction. A data output buffer is provided for cascading devices. This output reflects the current status of the last bit of the shift register (32). Operation of the shift register is not affected by the LE (latch enable) or the OE (output enable) inputs. Transfer of data from the shift register to the latch occurs when the LE input is high. The data in the latch is retained when LE is low.

The HV5522 is a low-voltage serial to high-voltage parallel converter with open drain outputs. This device has been designed for use as a driver for AC-electroluminescent displays. It can also be used in any application requiring multiple output high voltage current sinking capabilities such as driving inkjet and electrostatic print heads, plasma panels, vacuum fluorescent, or large matrix LCD displays. This device consists of a 32-bit shift register, 32 latches, and control logic to perform the polarity select and blanking of the outputs. Data is shifted through the shift register on the high to low transition of the clock. The HV5522 shifts in the counter clockwise direction when viewed from the top of the package. A data output buffer is provided for cascading devices. This output reflects the current status of the last bit of the shift register. Operation of the shift register is not affected by the LE (latch enable), BL (blanking), or the POL (polarity) inputs. Transfer of data from the shift register to the latch occurs when the LE (latch enable) input is high. The data in the latch is stored when LE is low.

The HV56020 is a dual amplifier with integrated boost for driving piezo actuators for haptic applications, such as Kemet film actuators, and other solutions. The HV56020 comes with 3 functions, specifically, dual 250V operational amplifiers, a boost controller, and a power MOSFET. The opamps are designed to drive haptic (piezo) actuators at 225V with 40 mA minimum source/sink current. The boost controller and power MOSFET along with an external transformer generate the voltage supply for the HV opamps using a non-Isolated flyback configuration. The HV56020 is the master IC between the HV56020 and HV56022, with the inclusion of the boost converter versus simply the dual amplifier array of the HV56022. The drive channel count is supportable by expanding with additional HV56020s if additional power is required for simultaneous drive of multiple channels (beyond two,) or with HV56022s if the additional channels can be driven time-sliced versus those drawing power from the first HV56020 boost converter. The HV56020 also includes a variety of protection features, including Over/Under Voltage Protection, Output Short Circuit Protection (DC-to-DC), Temperature Sensor, and Output Voltage Comparators for load Short Circuit Detection. **Microchip has partnered with Kemet to create this chipset that optimizes size and features for driving thin-film actuators that enable haptic applications in various hard and soft goods.** [**Learn more >>**](https://www.microchip.com/en-us/products/interface-and-connectivity/dc-dc-high-voltage-interface-drivers-amplifiers-arrays/mems-piezoelectric-drive/haptics/thin-film-actuator)
