产品概述

描述

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).
