STMicroelectronics STGIB15CH60S-L

Overview

STGIB15CH60S-L from STMicroelectronics is a 20 A, 600 V SLLIMM-2nd series intelligent power module (IPM) integrating a 3-phase IGBT inverter bridge, high- and low-side gate drivers, bootstrap diodes, temperature sensor, and fault protection circuitry. It delivers short-circuit rugged trench-gate field-stop IGBTs with 5 µs withstand time at 300 V, soft-recovery freewheeling diodes, and 1600 V_rms/min isolation for motor drive inverters operating up to 20 kHz.

For engineers reviewing the STGIB15CH60S-L datasheet, STGIB15CH60S-L pinout, STGIB15CH60S-L application, or STGIB15CH60S-L equivalent, key selection considerations include TTL/CMOS-compatible 3.3 V/5 V inputs with hysteresis, smart shutdown response ≤24 µs for overcurrent, separate open-emitter outputs, and integrated thermal sensing via TSO pin voltage (1.16 V typ. at 25 °C).

Technical Context

The module integrates two proprietary ST control ICs-one high-side (HS) and one low-side (LS) driver-each featuring undervoltage lockout (UVLO) with hysteresis (1.2–1.7 V for VCCH, 1.1–1.6 V for VCCL) and internal bootstrap diodes. Gate drive logic supports active-high 3.3 V/5 V TTL/CMOS inputs with built-in 100 kΩ pull-down resistors.

Fault management uses a dedicated comparator with 460–560 mV internal reference, enabling fast overcurrent detection via external shunt resistor on CIN; the smart shutdown architecture forces LVGx outputs low within ≤24 µs of fault detection-bypassing external RC delay dependence-while simultaneously asserting SD/OD as open-drain output.

Key Specifications

FAQ

What is the maximum recommended PWM frequency for STGIB15CH60S-L?

The device is characterized for operation up to 20 kHz in hard-switching topologies, with specified switching energies (E_on, E_off, E_rr) and thermal impedance validated at this frequency. Exceeding 20 kHz increases conduction losses and thermal stress beyond guaranteed performance limits, especially above 100 °C case temperature.

How does the smart shutdown function differ from conventional fault handling?

Unlike standard shutdown circuits that rely on external RC timing networks-and thus introduce variable, design-dependent delays-the smart shutdown asserts LVGx outputs low within ≤24 µs of CIN comparator triggering, independent of SD pin RC values. This ensures deterministic, ultra-fast protection while allowing large RC time constants for extended fault hold-off without compromising response speed.

Can STGIB15CH60S-L be used without an external bootstrap capacitor?

No. Although the module integrates internal bootstrap diodes, external bootstrap capacitors (C_BOOT) are mandatory for high-side gate drive. Each V_BOOT pin (U/V/W) requires its own 0.22–1 µF low-ESR/low-ESL capacitor placed directly between V_BOOT and corresponding phase output (U/V/W), as specified in Figure 8 and Section 6.1 of DS11875.

What is the purpose of the dual GND pins (pins 9 and 16)?

Pins 9 and 16 are separate control-ground returns for the high-side and low-side driver sections respectively. They must be connected to a common control ground plane-but kept physically distinct from power ground (PWR_GND) until a single-point tie near the shunt resistor-to prevent noise coupling into gate drive signals and ensure stable UVLO thresholds and logic input referencing.
