STMicroelectronics IPS8160HQ

Overview

IPS8160HQ from STMicroelectronics is an octal high-side driver IC built on VIPower M0-3 technology, designed to switch DC-13 loads per EN 60947-5-1 with 0.7 A steady-state output current per channel, CMOS-compatible 3.3 V logic inputs, and integrated thermal/overcurrent protection. It operates from 11.5–32 V supply, delivers 125 mΩ typical ON-resistance at 25 °C, and features a common open-source STATUS pin for junction overtemperature fault reporting.

For engineers reviewing the IPS8160HQ datasheet, IPS8160HQ pinout, IPS8160HQ application, or IPS8160HQ equivalent, this device is selected for industrial PLC I/O modules, NC machine tool control, vending machine load management, and systems requiring UL 2367-certified high-side switching with thermal independence across eight channels.

Technical Context

The IPS8160HQ integrates eight independent high-side power switches with active current limitation, dual-stage thermal protection (junction shutdown at 150–200 °C, case shutdown at 125–135 °C), and loss-of-ground detection. Each channel uses internal sense-FET feedback to enforce 0.7 A DC current limit under overload.

It implements fast active clamp demagnetization (V_DEMAG = V_CC−52 V) for inductive loads and supports reverse polarity protection via external resistor or diode. The STATUS pin asserts high during any channel's junction overtemperature event, with automatic restart hysteresis of 7–15 °C.

Key Specifications

Pinout & Package

IPS8160HQ is housed in a QFN48L 8×6×0.9 mm package with exposed thermal pad (EP = V_CC). The package supports high-power dissipation (R_th(JC) = 1.5 °C/W per channel) and requires PCB thermal vias under the EP for reliable operation at full load.

FAQ

What is the maximum continuous output current per channel for IPS8160HQ?

The IPS8160HQ delivers 0.7 A DC steady-state output current per channel, with internal current limiting activating at approximately 0.7 A (typical) and peaking up to 2.6 A before hard limiting. This rating is guaranteed across the full operating ambient temperature range of −40 °C to +85 °C and supply voltage range of 11.5–32 V.

How does the STATUS pin behave during thermal fault conditions?

The STATUS pin is an open-source output that pulls high when any channel's junction temperature exceeds TJSD (150–200 °C). It remains asserted until all faulted channels cool below TR (135 °C). During case overtemperature (TC > 125–135 °C), STATUS also activates but only after junction shutdown fails to resolve the condition-ensuring prioritized thermal response.

Can IPS8160HQ drive inductive loads without external flyback diodes?

Yes. The device integrates active clamp demagnetization with V_DEMAG = V_CC−52 V, enabling safe energy dissipation during inductive turn-off without external diodes. This feature supports DC-13 load switching per EN 60947-5-1 and eliminates board space and reliability risks associated with discrete clamp components.

Is the IPS8160HQ pin-compatible with the IPS8160HQ-1 variant?

No. While both share the same QFN48L package and pinout, the IPS8160HQ-1 is rated for 1.0 A per channel and exhibits different current-limiting thresholds (ILIM = 1.7 A vs. 0.7 A) and ON-resistance (160 mΩ vs. 125 mΩ typ). Substitution requires validation of load current, thermal margin, and protection timing behavior.
