STMicroelectronics STGIPS35K60L1

Overview

STGIPS35K60L1 from STMicroelectronics is a single-phase SLLIMM™ intelligent power module integrating short-circuit rugged 600 V / 35 A IGBTs, gate drivers, bootstrap diodes, fault protection comparators, and an op-amp for current sensing - designed for compact AC motor drives in air conditioner compressors. It features 2500 V_rms/min isolation, DBC substrate with 1.25 °C/W junction-to-case thermal resistance, and UL1557 recognition (E81734).

For engineers reviewing the STGIPS35K60L1 datasheet, STGIPS35K60L1 pinout, STGIPS35K60L1 application in inverter design, or STGIPS35K60L1 equivalent for HVAC compressor drives, this page delivers verified electrical ratings, SDIP-22L package layout, dead-time configuration via external resistor, smart shutdown timing, and NTC-based temperature monitoring with 4.7 kΩ @ 25°C.

Technical Context

The STGIPS35K60L1 integrates high-side and low-side gate drivers with interlocking logic and programmable dead time (via external R_DT), enabling robust half-bridge operation without external shoot-through protection. Its control section includes CMOS/TTL-compatible 3.3 V/5 V/15 V inputs, undervoltage lockout on both VCC and VBOOT, and a dedicated open-drain fault output (SD/OD) with priority path for immediate driver shutdown upon overcurrent detection.

It embeds a precision op-amp (±6 mV offset, 8–12 MHz GBWP) for shunt-based phase current sensing and a comparator with 90–130 ns propagation delay for fast overcurrent response. The integrated 4.7 kΩ NTC thermistor (B = 3950 K) enables real-time case temperature monitoring across –40 to +150 °C, supporting thermal derating and system-level protection.

FAQ

What is the maximum recommended PWM frequency for STGIPS35K60L1?

The datasheet specifies a recommended maximum PWM frequency of 20 kHz for operation within the full temperature range (–40 to +100 °C case temperature). This limit ensures safe junction temperature rise and accounts for switching losses (E_on + E_off = 1440 µJ typical), gate drive capability, and thermal resistance (R_thJC = 1.25 °C/W). Exceeding 20 kHz requires derating output current or enhancing heatsinking.

How is the dead time configured on STGIPS35K60L1?

Dead time is set externally via a resistor (R_DT) connected between pin 9 (DT) and GND. The value determines blanking duration: 0 kΩ yields ~1 µs, while 300 kΩ yields ~3.5 µs. This resistor adjusts internal monostable timing to prevent cross-conduction during HIN/LIN transitions. No software or register configuration is needed - it is purely analog hardware control.

Does STGIPS35K60L1 support direct MCU connection without optocouplers?

Yes. STGIPS35K60L1 integrates a high-voltage level-shifting IC (HVIC) that allows direct connection of 3.3 V or 5 V MCU GPIOs to HIN/LIN pins. Its built-in pull-down (HIN) and pull-up (LIN) resistors, along with noise-immune hysteresis, eliminate the need for external optocouplers or level shifters - reducing bill-of-materials and PCB footprint in cost-sensitive HVAC designs.

What is the role of the SD/OD pin in fault handling?

Pin 7 (SD/OD) serves dual roles: as an active-low shutdown input (driven by MCU or comparator) and as an open-drain fault output. When overcurrent is detected at CIN, the internal smart shutdown logic immediately disables both gate drivers (<250 ns delay) and pulls SD/OD low. This same pin can then signal fault status back to the controller - enabling bidirectional, single-wire fault communication without additional pins or components.
