Product details

Overview

STIPN2M50T-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 NDIP-26L package. It delivers 3-phase inverter functionality with R_DS(on) ≤ 1.7 Ω, ±2 kV HBM ESD protection, and integrated op-amp/comparator for current sensing and fault protection - deployed in refrigerator compressors and air-conditioning fan drives.

For engineers reviewing the STIPN2M50T-H datasheet, STIPN2M50T-H pinout, STIPN2M50T-H application, or STIPN2M50T-H equivalent, this page provides verified technical context, validated pin functions, real-world motor drive use cases, and confirmed alternative IPMs with documented functional differences.

Technical Context

This IPM implements a fully integrated 3-phase inverter bridge with independent high- and low-side gate drivers per phase, each featuring interlocking logic and 180 ns dead-time generation to prevent shoot-through. The control section includes a rail-to-rail op-amp (8–12 MHz GBWP, 2.5–3.8 V/µs slew rate) and a comparator with 0.54 V internal reference for fast overcurrent detection.

Thermal design is enabled by a 10.6 °C/W junction-to-case thermal resistance per MOSFET and an NTC thermistor internally connected to dual T/SD/OD pins (pins 2 and 15), supporting temperature monitoring with pull-up resistor–based voltage scaling (e.g., 2.2 kΩ for 5 V MCU systems).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	500 V - blocking voltage rating per MOSFET, enabling operation with 400 V DC bus (recommended 300–400 V).
I_D	2 A continuous - maximum RMS output current per phase at T_C = 25 °C, derated above 100 °C case temperature.
R_DS(on)	1.7 Ω max - on-resistance determines conduction loss and thermal rise under load; impacts efficiency in <1 kW motor drives.
V_ISO	1000 V_rms - isolation withstand voltage between all pins and heatsink, meeting UL 1434 Class 2 & 4 requirements.
t_dead	1 µs - programmable blanking time prevents false triggering during switching transitions; set via external RC on CIN.
T_J	−40 to +150 °C - operational junction temperature range, supporting sealed compressor environments and outdoor HVAC units.
V_CC	13.5–18 V - control supply range compatible with standard 15 V regulators; UVLO thresholds at 12.0 V (ON) / 10.5 V (OFF).

Pinout & Package

NDIP-26L (Type C) is a 26-pin, single-in-line, insulated plastic package with integrated heatsink pad and optimized thermal path. Pin 1 is marked with a notch; pin 16 is a dummy pin internally tied to P (positive DC input). The layout supports compact PCB routing with dedicated bootstrap, phase output, and isolated control terminals.

Pin/Terminal	Circuit Role	Design Meaning
1 GND	Power ground reference	Common return for control circuitry and low-side driver references; must be star-connected near shunt resistor.
2 & 15 T/SD/OD	NTC terminal / shutdown input / open-drain fault output	Dual-function pin: monitors temperature via internal NTC; accepts active-low shutdown signal; outputs fault status as open-drain.
3, 9, 13 V_CCW/V/U	Low-voltage supply per phase	Independent 15 V supplies for each HVIC; decoupling required per pin to suppress switching noise coupling.
4, 10, 14 HIN W/V/U	High-side logic input	Active-high CMOS/TTL input (2.25 V threshold); internal 375 kΩ pull-down prevents floating; RC filter recommended.
5, 11, 16 LIN W/V/U	Low-side logic input	Active-high input with same bias and filtering requirements as HIN; enables independent PWM control per leg.
6 OP+, 8 OP−, 7 OPOUT	Uncommitted op-amp	Fully differential amplifier (±14.7 V output swing) for current sensing amplification or analog signal conditioning.
12 CIN	Comparator non-inverting input	Accepts shunt voltage; compares against 0.54 V internal reference; 90–130 ns propagation delay enables fast overcurrent response.
17, 21, 24 VBOOT U/V/W	Bootstrap voltage input	Supplies high-side gate driver; requires ceramic capacitor (100–220 nF) placed directly at pin to sustain 18 V bias during PWM.
18 P, 20 N_U, 23 N_V, 26 N_W	DC bus terminals	P = positive DC input; N_U/N_V/N_W = negative returns per phase - low-inductance layout critical to limit voltage spikes.
19 U,OUT, 22 V,OUT, 25 W,OUT	Phase output terminals	Direct connections to motor windings; rated for 500 V blocking and 2 A continuous; require short, wide traces to minimize EMI.

Key Features

Feature	Design Value
Integrated op-amp	8–12 MHz gain-bandwidth product and 2.5–3.8 V/µs slew rate enable precise, wideband current sensing without external amplifiers.
Interlocking logic	Hardware-enforced 180 ns dead time between complementary HIN/LIN signals prevents shoot-through without MCU firmware intervention.
NTC-based thermal monitoring	Dual T/SD/OD pins support redundant temperature sensing; internal NTC curves match UL 1434 Class 2/4 compliance for appliance safety.
Internal bootstrap diodes	Eliminates need for external bootstrap diodes; reduces BOM count and layout area while maintaining reliable high-side gate drive.
±2 kV HBM ESD protection	Robust input protection allows direct MCU interface without optocouplers, reducing system cost and latency in embedded motor control.

Applications

Use Value: Achieves CISPR-11 Class B EMI compliance without external snubbers; built-in bootstrap diodes simplify power supply design.

Dishwasher Drain Pump Control

Recirculation Pump for HVAC Systems

Use Scenario: High-torque, intermittent-duty drain pump in residential dishwashers, subject to moisture, vibration, and thermal cycling.

IC Role / Device Role / Timing Role: Compact IPM delivering robust 3-phase drive with integrated fault protection - operates from 300 V DC bus derived from rectified mains.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-phase inverter IPM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
FSB50450	Higher current rating (4.5 A), 600 V blocking, larger DIP-25 package; no integrated op-amp or NTC.	Better suited for >500 W industrial pumps; lacks on-module analog sensing, requiring external amplification.	Select when higher power density and extended voltage margin are needed, and external signal conditioning is acceptable.
STIPN2M50T-Z	Same electrical specs and pinout, but NDIP-26L Type Z package with different mechanical dimensions and thermal pad layout.	Not interchangeable mechanically; requires PCB redesign due to altered pin pitch and heatsink mounting geometry.	Choose only for new designs where Type Z's enhanced thermal performance justifies layout rework and qualification.

Compared with FSB50450, STIPN2M50T-H trades peak current capacity for integrated analog functions and compactness - ideal for space-constrained white goods. Against STIPN2M50T-Z, it offers identical electrical behavior but simplified mechanical integration in legacy NDIP-26L Type C layouts.

FAQ

What is the maximum recommended DC bus voltage for STIPN2M50T-H?

The absolute maximum V_DSS is 500 V, but the recommended operating voltage is 300–400 V DC (per Table 14). Exceeding 400 V increases risk of avalanche stress during transients and reduces safe operating area margins, especially at elevated temperatures.

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

Yes - the op-amp (pins OP+, OP−, OPOUT) has rail-to-rail output (0–14.7 V), 8–12 MHz GBWP, and 2.5–3.8 V/µs slew rate, making it suitable for amplifying shunt resistor voltages in real-time current loops. Its uncommitted nature allows configurable gain and filtering without external components.

How does the dual T/SD/OD pin configuration improve system safety?

Pins 2 and 15 both connect to the same internal NTC and share shutdown/fault functions. This enables redundant temperature monitoring paths - if one pin fails open or shorted, the other maintains thermal protection, satisfying IEC 60730 Class B and UL 1434 fault tolerance requirements for household appliances.

Is external bootstrap diode required for high-side gate drive?

No - STIPN2M50T-H integrates internal bootstrap diodes for all three phases (U/V/W), eliminating the need for external diodes. This reduces component count, PCB area, and potential failure points while maintaining reliable bootstrap capacitor recharge during continuous PWM operation.
