STMicroelectronics IPS8200HQ

Overview

IPS8200HQ from STMicroelectronics is an octal high-side smart power solid-state relay with selectable SPI/parallel interface, designed for industrial I/O driving. It delivers 0.7 A per channel (continuous), operates from 10.5 V to 36 V, integrates a 100 mA adjustable DC/DC regulator and 4×2 LED matrix, and supports programmable logic control systems with per-channel overload, short-circuit, and independent junction/case overtemperature protection.

For engineers reviewing the IPS8200HQ datasheet, IPS8200HQ pinout, IPS8200HQ application, or IPS8200HQ equivalent, this device serves as a fault-protected, diagnostics-rich high-side driver for PLC output modules, CNC peripheral interfaces, and industrial PC I/O cards-where supply robustness, channel independence, and real-time diagnostic reporting are critical.

Technical Context

The IPS8200HQ implements ST's VIPower™ technology to enable monolithic integration of eight high-side power switches, each with active current limiting (0.7 A typ.), fast demagnetization clamping (V_OUT clamp), and loss-of-GND detection. Its dual-mode interface allows flexible system integration: SPI mode supports 5 MHz daisy-chain operation with parity-checked 8-/16-bit frames and MCU freeze detection, while parallel mode enables direct GPIO-level control of all eight channels via dedicated INx pins.

Built-in diagnostics include three open-drain outputs-FAULT (junction overtemp/SPI fault), TWARN (case overtemperature), and PG (VCC under/overvoltage)-all referenced to VREG and pulled up externally. The integrated step-down regulator (400 kHz, 100 mA) supplies VREG at 3.3 V or 5 V, with FB pin enabling external voltage adjustment, and features peak-current control and short-circuit foldback.

FAQ

What is the maximum continuous output current per channel for IPS8200HQ?

The IPS8200HQ delivers 0.7 A continuous output current per channel at TJ ≤ 125 °C, with internal current limiting activating at ~1.4 A peak before thermal shutdown. This rating assumes proper PCB copper pour and thermal vias to maintain R_th(JC) ≤ 1 °C/W, as specified in the DS14313 datasheet Section 3.

Can IPS8200HQ drive inductive loads safely without external flyback diodes?

Yes-IPS8200HQ includes integrated V_OUT clamping that actively limits turn-off voltage to VCC − 45 V (min), enabling safe demagnetization of inductive loads up to 1 mH at 0.5 A without external diodes. This is confirmed in Section 4.5 (Table 8) and Figure 7 of DS14313 Rev 3.

How does the watchdog function operate, and what triggers its reset?

The watchdog resets the internal logic when the WD pin receives a falling edge before timeout expires. Timeout duration is set by WD_EN voltage (0–VREG), ranging from 50 ns to >100 ms. If WD_EN is held low, watchdog is disabled; if >25% VREG, it activates with programmable hold time tWD = tWM + td(OFF), per Section 4.5 Table 8.

Is the integrated DC/DC regulator adjustable, and what is its output accuracy?

Yes-the DC/DC output is adjustable via the FB pin: connecting FB to DCVDD yields 3.3 V (±3%), while a resistor divider enables 5 V or other values. Accuracy is ±3% over load (0–100 mA) and temperature (−40 °C to 125 °C), as verified in Table 9 (Section 4.6) of DS14313 Rev 3.
