STMicroelectronics STIPQ3M60T-HL

Overview

STIPQ3M60T-HL from STMicroelectronics is a SLLIMM™-nano 2nd series intelligent power module (IPM) integrating six 600 V N-channel MDmesh™ DM2 MOSFETs and three half-bridge HVIC gate drivers in a single N2DIP-26L package. It delivers 3 A continuous 3-phase inverter output with R_DS(on) ≤ 1.6 Ω, built-in op-amp for current sensing, comparator-based overcurrent/overtemperature protection, and NTC thermistor for thermal monitoring - deployed in compact motor drives for refrigeration compressors and HVAC fans.

For engineers reviewing the STIPQ3M60T-HL datasheet, STIPQ3M60T-HL pinout, STIPQ3M60T-HL application, or STIPQ3M60T-HL equivalent, key selection criteria include its integrated smart shutdown architecture, 1500 V_rms/min isolation rating, bootstrap-diode-equipped high-side drive, and dual-function T/SD̅̅̅̅/OD pin supporting both NTC sensing and open-drain fault signaling.

Technical Context

This IPM implements a fully integrated 3-phase inverter bridge with independent U/V/W half-bridge sections, each featuring dedicated V_CC, HIN/LIN, V_BOOT, and OUT pins. Gate driving uses high-voltage ICs (HVICs) with interlocking logic and 180 ns programmable dead time to prevent shoot-through, while internal bootstrap diodes eliminate external diode placement.

The control section includes a rail-to-rail op-amp (±14.7 V output swing, 3.8 V/µs slew rate), a precision comparator (0.54 V reference, 130 ns propagation delay), and shared T/SD̅̅̅̅/OD pin that multiplexes NTC voltage sensing, active-low shutdown input, and open-drain fault output - all referenced to GND and compatible with 3.3 V/5 V/15 V CMOS/TTL logic.

FAQ

What logic voltage levels does STIPQ3M60T-HL support for HIN/LIN inputs?

STIPQ3M60T-HL accepts 3.3 V, 5 V, and 15 V CMOS/TTL logic levels on all HIN and LIN pins. Each input features an internal 375 kΩ pull-down resistor, and the high-level threshold is 2.25 V minimum, ensuring reliable operation across standard MCU I/O voltages without level-shifting circuitry.

How is thermal protection implemented using the T/SD̅̅̅̅/OD pin?

The T/SD̅̅̅̅/OD pin connects internally to an NTC thermistor and a comparator. As temperature rises, NTC resistance drops, lowering the pin voltage. When this voltage falls below the logic low threshold (≤0.8 V), the device triggers smart shutdown. A 1 kΩ or 2.2 kΩ external pull-up resistor sets the trip point for 3.3 V or 5 V MCUs respectively.

Can the integrated op-amp be used for motor phase current sensing?

Yes - the uncommitted op-amp (pins OP+, OP−, OPOUT) is explicitly designed for current sensing. With external gain-setting resistors, it amplifies the differential voltage across a low-value shunt resistor placed on the NU/NV/NW paths, enabling precise real-time phase current measurement without additional signal-conditioning ICs.

What is the purpose of the interlocking function and how is it configured?

The interlocking function prevents simultaneous high-side and low-side MOSFET conduction in any half-bridge by enforcing hardware-enforced dead time (180 ns typical). It is automatic and requires no external configuration - activated whenever HIN and LIN on the same phase are driven high concurrently, forcing both LVG and HVG outputs low until the conflict resolves.
