IPS160HFSingle channel high-side switches | Integrated Circuits (ICs) | 2 | Active | The IPS160HF (Iout < 2.5 A) and IPS161HF (Iout < 0.7 A) are monolithic devices which can drive capacitive, resistive or inductive loads with one side connected to ground.
The 60 V operating range and Ron = 60 mΩ, combined with the extended diagnostic (Open Load, Over Load, Overtemperature) and the < 60 us propagation delay time at startup (enabling Class 3 for interface types C and D), make the IC suitable for applications implementing the proper architectures to address higher SIL levels.
The built-in overload and thermal shutdown protections guarantee the ICs, the application and the load against electrical and thermal overstress. Furthermore, in order to minimize the power dissipation when the output is shorted, a low-dissipative short-circuit protection (cut-off) is implemented to limit the output average current value and consequent device overheating. Cut-off delay time can be set by soldering an external capacitor or disabled by a resistor on pin 4 (CoD).
The DIAG common diagnostic open drain pin reports the open load in off-state, cut-off (overload) and thermal shutdown. |
IPS2050HHigh efficiency, high-side switch with extended diagnostics and smart driving for capacitive loads | Power Distribution Switches, Load Drivers | 1 | Active | The IPS2050H/HQ and IPS2050H-32/HQ-32 are dual high-side switch ICs able to drive capacitive, resistive or inductive loads with one side connected to ground.
The very low RDS-ON(≤ 50 mΩ up to TJ= 125 °C) makes the IC suitable for applications with up to 2.4 A (IPS2050H/HQ) or 5.6 A (IPS2050H-32/HQ-32) steady state operating current.
Each output channel is independently protected against junction over-temperature events by a junction temperature sensor, and a further temperature sensor is included to monitor case temperature, so an overheated output channel can only be turned back ON when the case temperature returns below the reset temperature.
The embedded per-channel overload protection circuit monitors the output current and, on triggering of the activation threshold (IPK-X), starts modulating the impedance of the output switch to limit the output current to ILIM-X, for both IC and load protection.
The IC offers two different sets of activation threshold and limitation levels (IPKH-X, ILIMH-Xand IPKL-X, ILIML-X) for smart driving of capacitive loads (such as bulb lamps) and loads with initial peak current requirements.
The IC diagnostics is based on two FAULT pins (current source), one for each channel. Each FAULT pin is activated by an overload or an over-temperature event on the related channel. |

IPS8200HQOctal high-side smart power solid-state relay with serial/parallel selectable interface on-chip | Power Management (PMIC) | 1 | Active | The IPS8200HQ and IPS8200HQ -1 are monolithic 8-channel drivers, designed using STMicroelectronics™ VIPower™ technology, and intended to drive any kind of load with one side connected to the ground. Both ICs operates from 10.5 V to 36 V and feature a very low supply current, parallel or 4-wire SPI control interface, a 4x2 LED matrix, and a micropower step-down switching regulator with a peak current control loop mode.
The SPI interface (enabled by SEL2 pin = H) can work up to 5 MHz in 8-bits (SEL1 = L), or 16-bits (SEL1 = H) with a parity check and extended diagnostic (DC/DC operation, case overtemperature, SPI Communication Fail, and Power Good) information. In SPI mode the daisy chain is allowed, and both the OUT_EN signal and the MCU freeze detection by watchdog are available. If enabled (WD_EN voltage above 25% of VREG), the watchdog circuitry generates an internal reset on expiry of the internal watchdog timer. The watchdog timer reset can be achieved by applying a negative pulse on the WD pin. The watchdog timer can be programmed by the set voltage on the WD_EN pin.
The internal LED matrix driver circuitry (4 rows, 2 columns) allows the efficient driving of the 8 LEDs reporting the on/off status of each of the 8 outputs. The VREG pin supplies both the logic output buffers and LED matrix. The 100 mA output current capability of the integrated step-down (featuring overload and short-circuit conditions) can be used to supply both the VREG pin and other application components (for example: digital isolators or optocouplers).
Active per-channel current limitations (0.7 A and 1.0 A for IPS8200HQ and IPS8200HQ-1, respectively), combined with channel-independent thermal shutdown, protect the circuitry against overload and short circuits. Built-in thermal shutdown protects each channel from overtemperature and overload: each overheated channel automatically turns OFF after its junction temperature triggers the protection threshold (TTSD). The channel turns back ON if its junction temperature decreases lower than the restart threshold (TR). An additional case temperature sensor protects the whole chip against overtemperature: if the case temperature triggers the TCSD threshold then overloaded channels are turned OFF and restart only when the case temperature decreases to the reset threshold (TCR). Non-overloaded channels continue to operate normally.
Loss of GND protection guarantees automatic turn-off of the outputs in case of a ground wire break.
Dedicated diagnostic pins report the detection of: invalid voltage range on VCC rail (PG pin), caseovertemperature (TWARN pin), SPI fault, or junction overtemperature (FAULT pin). |
