STMicroelectronics STIPNS2M50T-H

Overview

STIPNS2M50T-H from STMicroelectronics is a SLLIMM-nano intelligent power module (IPM) integrating six 500 V, 2 A MOSFETs and three half-bridge HVIC gate drivers in a single NSDIP-26L package. It delivers 3-phase inverter functionality with R_DS(on) ≤ 1.7 Ω, built-in op-amp and comparator for current sensing/protection, and NTC-based thermal monitoring - designed for compact, low-EMI motor drives up to 100 W.

For engineers reviewing the STIPNS2M50T-H datasheet, STIPNS2M50T-H pinout, STIPNS2M50T-H application, or STIPNS2M50T-H equivalent, this IPM supports direct MCU interfacing (3.3 V/5 V/15 V logic), features interlocking and shutdown functions, includes internal bootstrap diodes, and provides real-time overcurrent and temperature fault detection via dedicated CIN and T/SD/OD pins.

Technical Context

This IPM implements a fully integrated 3-phase inverter stage with independent U/V/W half-bridge gate drivers, each incorporating level-shifting HVICs, undervoltage lockout (V_CC UVLO: 12.0 V turn-on, 10.5 V turn-off), and dead-time control (180 ns). The embedded op-amp (GBWP: 8–12 MHz, SR: 2.5–3.8 V/µs) and comparator (V_REF: 0.54 V typ., t_{d_comp}: 90–130 ns) enable fast analog current sensing without external signal conditioning.

The module integrates an NTC thermistor internally connected to dual T/SD/OD pins (pins 2 and 15), with pull-down resistors enabling temperature-dependent voltage monitoring (e.g., 4.5 V at 25 °C → 2.5 V at 125 °C with 5 V bias). Its isolation rating is 1000 V_rms, junction temperature range is −40 to +150 °C, and thermal resistance (R_th(j-c)) is 11.7 °C/W per MOSFET.

FAQ

What logic voltage levels does STIPNS2M50T-H support for HIN/LIN inputs?

STIPNS2M50T-H supports 3.3 V, 5 V, and 15 V CMOS/TTL logic levels on all HIN and LIN inputs. Each input has a built-in 375 kΩ pull-down resistor, and the high-level threshold is 2.25 V minimum (V_IH), while the low-level threshold is 0.8 V maximum (V_IL). This ensures compatibility with common microcontrollers without level-shifting circuitry.

How is overcurrent protection implemented in this IPM?

Overcurrent protection uses an internal comparator with a fixed 0.54 V reference voltage applied to its inverting input. The non-inverting input (CIN pin) connects to an external shunt resistor. When sensed voltage exceeds 0.54 V, the comparator triggers within 90–130 ns, disabling the U-phase outputs directly and propagating shutdown to V/W phases via external RC timing on the T/SD/OD pin.

Can the integrated op-amp be used for closed-loop motor control?

Yes - the uncommitted op-amp has rail-to-rail output swing (up to 14.7 V), 8–12 MHz gain-bandwidth product, and 2.5–3.8 V/µs slew rate, making it suitable for implementing PI current regulators or voltage amplifiers in sensorless FOC or V/f control schemes. It operates from the same V_CC supply as the gate drivers and shares the GND reference.

What thermal protection mechanisms are built into STIPNS2M50T-H?

The IPM integrates a UL 1434-certified NTC thermistor internally connected to pins 2 and 15 (T/SD/OD). As temperature rises, the voltage at these pins decreases predictably (e.g., from 4.5 V at 25 °C to ~2.5 V at 125 °C with 5 V bias), allowing the MCU to implement thermal foldback or shutdown. The module also includes undervoltage lockout on both V_CC and V_BOOT to prevent unsafe operation under thermal stress-induced supply droop.
