NCV7692Current Controller for Automotive LED Lamps | Development Boards, Kits, Programmers | 2 | Active | The NCV7692 is a device which uses an external NPN bipolar device combined with feedback resistor(s) to regulate a current for use in driving LEDs. The target application for this device is automotive rear combination lamps. A single driver gives the user flexibility to add single channels to multichannel systems. A dedicated dimming feature is included via the PWM input pin. The individual driver is turned off when an open load or short circuit is detected. LED brightness levels are easily programmed using an external resistor in series with the bipolar transistor. The use of the resistor gives the user the flexibility to use the device over a wide range of currents. Multiple strings of LEDs can be operated with a single NCV7692 device. Set back power limit reduces the drive current during overvoltage conditions. The device is available in a SOIC−8 package. |

Each individual driver has its own diagnosticto detect open load, short circuit to ground or to battery.LED average brightness levels are easily programmed usingappropriate duty cycle control and external resistors in series with theswitching transistors.Multiple strings of LEDs can be operated with a single NCV7693device. The device is available in a TSSOP−14 package. |
NCV7694Safety Controller for Infra-Red LED Illumination to Complement the Image Sensor for Automotive Applications | LED Driver Evaluation Boards | 2 | Active | The NCV7694 is a device which can drive a string of infra−red LEDs using an external mosfet. The IR LEDs are used to illuminate the surroundings of the image sensor. Since these LEDs can damage the end users’ eyes, the power feed to the LEDs needs to be turned off during a fault condition.The NCV7694 driver features prevents the IR LEDs from being ON too long due to an inappropriate exposure time or being turned on too frequently using external resistors. The value of the RETL resistor defines the maximum TON time of the emitted light intensity and the value of the RFRL resistor defines the maximum frequency of the FLASH signal from the image sensor. A LED driver with hardware interlocks helps protect the users’ eyes in cases where the control signal has failed or a fault in the LED power path has occurred. LED brightness level is easily programmed using an external resistor in series with the mosfet transistor. The device can also detect Open Load, Short Circuit to GND and VS. Faults are reported to the DIAG pin, which can directly disable the DC/DC converter to prevent possible damage. The device is available in 10 pin DFN package. |

NCV7702BMotor Driver, Dual H-Bridge, 1.0 A | Power Management (PMIC) | 1 | Obsolete | This dual full−bridge driver IC is intended for 14 V automotive stepper and DC motor applications. Its four half−bridge outputs are configured as two channels and are programmed by six TTL compatible inputs, allowing flexible control of bridge operation. The device operates in standby mode, run mode, or brake mode and typically consumes less than 1 uA while in standby. In run mode, each half−bridge output can deliver load current in either direction. Brake mode activates the low side transistors or high side transistors at the selected outputs. On−chip recirculation diodes are provided, and the IC has multiple fault protection modes.Overcurrent detection protects against shorted loads between outputs and shorts to supply or ground at each output. An overcurrent fault condition activates an internal timer, which modulates faulted outputs at low duty cycle. An overcurrent condition in one channel does not affect operation in the other. Overvoltage and overtemperature detection are also provided, and turn off all bridge outputs during these fault conditions. Recovery from all fault conditions is automatic; the IC will resume normal operation in its previously selected mode upon fault resolution. Diagnostic ability is provided by two open−collector STATUS outputs which report the fault status of each channel independently during overcurrent faults, and together during overvoltage or overtemperature faults. |
NCV7703CTriple Half-Bridge Driver for automotive side-view mirror control. | Development Boards, Kits, Programmers | 4 | Active | The NCV7703B is a fully protected Triple Half-Bridge Driver designed specifically for automotive and industrial motion control applications. The three half-bridge drivers have independent control. This allows for high side, low side, and H-Bridge control. H-Bridge control provides forward, reverse, brake, and high impedance states. The drivers are controlled via a standard SPI (Serial Peripheral Interface). This device is fully compatible with ON Semiconductor's NCV7708B Double Hex Driver. |
