STMicroelectronics STGIPN3H60AT

Overview

STGIPN3H60AT from STMicroelectronics is a SLLIMM-nano intelligent power module integrating a 3 A, 600 V, 3-phase IGBT inverter bridge with integrated gate drivers, freewheeling diodes, bootstrap diodes, NTC thermistor (85 kΩ at 25 °C), and protection circuitry including undervoltage lockout and interlocking logic. It delivers low EMI motor drive capability for compact built-in appliance applications such as refrigerator compressors and dishwasher pumps.

For engineers reviewing the STGIPN3H60AT datasheet, STGIPN3H60AT pinout, STGIPN3H60AT application, or STGIPN3H60AT equivalent, this IPM supports 3.3 V/5 V/15 V CMOS/TTL logic inputs, features 320 ns dead time, negative V_CE(sat) temperature coefficient, and optimized NDIP-26L thermal layout - critical for reliable BLDC/PMSM control in space-constrained consumer and industrial systems.

Technical Context

This IPM implements three half-bridge high-voltage ICs (HVICs) driving six IGBTs with integrated freewheeling diodes, enabling direct MCU interface without optocouplers. Each phase includes independent V_CC, HIN/LIN inputs, V_BOOT, and OUT terminals, with internal pull-down resistors (500 kΩ typ.) on all logic inputs.

The control section integrates undervoltage detection on both V_CC (9.6 V turn-on threshold) and V_BOOT (9.5 V turn-on), interlocking logic to prevent shoot-through, and an uncommitted op-amp for custom protection circuits. The embedded 85 kΩ NTC (B = 4092 K) enables precise thermal monitoring per UL1434 CA2/CA4 compliance.

FAQ

What is the maximum allowable DC bus voltage for continuous operation?

The STGIPN3H60AT supports a recommended operating DC bus voltage of 300–500 V (VPN), with absolute maximum V_CES = 600 V. For reliable long-term operation, ST specifies 500 V as the upper limit under normal thermal conditions (T_C ≤ 100 °C), ensuring margin against transients and ripple-induced overvoltage.

How is the NTC thermistor wired for temperature monitoring?

The NTC (85 kΩ at 25 °C) connects across pins 2, 6, and 15 - all internally joined to one NTC terminal. The other terminal is GND (pin 1). A simple voltage divider with a fixed resistor (e.g., 82 kΩ) between V_CC and the NTC node provides analog voltage to an MCU ADC, calibrated per R-T curve in DS10613 Table 11.

Can the STGIPN3H60AT be driven directly by a 3.3 V microcontroller?

Yes - its HIN/LIN inputs accept 3.3 V logic levels (V_IL ≤ 1.1 V, V_IH ≥ 1.8 V) and include internal 500 kΩ pull-down resistors. No level-shifting circuitry is required, though RC filters (100 ns time constant) are recommended on each input to suppress EMI-induced glitches near switching nodes.

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

The interlocking function is a hardware-level safety feature that prevents simultaneous activation of HIN and LIN on the same phase. It is implemented inside the HVIC control logic: if HIN is high, the corresponding LIN is forced low, and vice versa - eliminating shoot-through risk even during MCU software faults or signal noise events.
