Product details

Overview

STIPN1M50T-H from STMicroelectronics is a SLLIMM-nano intelligent power module (IPM) integrating six 500 V, 1 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) ≤ 3.6 Ω, built-in op-amp for current sensing, comparator-based fault protection, and NTC thermistor for temperature monitoring - deployed in compact motor drives such as air-conditioning fans and roller shutters.

For engineers reviewing the STIPN1M50T-H datasheet, STIPN1M50T-H pinout, STIPN1M50T-H application, or STIPN1M50T-H equivalent, this page provides verified technical context, validated pin functions, real-world motor control use cases, and confirmed alternative IPMs with documented functional trade-offs.

Technical Context

The STIPN1M50T-H implements a fully integrated 3-phase inverter topology with independent high-side and low-side logic inputs (HIN/LIN per phase), internal bootstrap diodes, and interlocking logic to prevent shoot-through. Its control section includes a rail-to-rail op-amp (GBWP = 8–12 MHz, SR = 2.5–3.8 V/µs) and a comparator with 0.54 V internal reference for overcurrent detection via external shunt resistors.

Thermal management is enabled by dual NTC terminals (pins 2 and 15) tied to an internal thermistor network with pull-down resistors (125 kΩ equivalent), supporting temperature-dependent shutdown with <500 ns activation time. The module supports 3.3 V/5 V/15 V CMOS/TTL logic inputs and features ±2 kV HBM ESD protection on all digital pins.

Pinout & Package

NDIP-26L is a 26-pin, single-row, molded DIP package with internal heatsink pad (exposed metal base) optimized for thermal dissipation in space-constrained motor modules. Pin 1 is marked by notch; pin 16 is dummy (internally connected to P).

1 GND	Power ground reference	Common return for all low-voltage control circuitry and op-amp biasing.
2 & 15 T/SD/OD	NTC terminal / shutdown input / open-drain output	Triple-function pin: connects to internal NTC for temp sensing, accepts active-low shutdown signal, outputs fault status.
3, 9, 13 V_CCW/V/U	Low-voltage supply per phase	Independent 15 V supplies for each HVIC, decoupled separately to suppress noise coupling between phases.

8 OP−	Op-amp inverting input	Used with external feedback network to set gain; input bias current 100–200 nA enables high-impedance designs.
12 CIN	Comparator input	Accepts voltage from shunt resistor; compared against 0.54 V internal reference for overcurrent trip.
17, 21, 24 V_BOOTU/V/W	Bootstrap capacitor connection	Drives high-side gate via external bootstrap capacitor; supports 620 V max voltage swing.
18 P	Positive DC bus input	Main high-voltage DC input node; electrically isolated from control pins by 1000 V_rms barrier.
19, 22, 25 U/V/W,OUT	Phase output terminals	Direct connections to motor windings; rated for 500 V blocking and 1 A continuous current.
20, 23, 26 N_U/N_V/N_W	Negative DC bus returns	Separated low-side return paths per phase, minimizing ground loop interference in multi-leg layouts.

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
FSTI1M50T-H	Same NDIP-26L package, identical 500 V/1 A rating, but lacks integrated op-amp and NTC support.	Suitable only for basic inverter functions where external current sensing and temperature monitoring are implemented separately.	Select when cost sensitivity outweighs integration benefits and system-level sensing is already available.
FSB50550	Higher current rating (5 A), larger DIP-26 package, no op-amp or NTC; uses external bootstrap capacitors only.	Targeted at higher-power pumps/fans (>100 W), requiring external gate drivers and protection circuitry.	Choose for scalability beyond 1 A, accepting increased board area and design effort for added headroom.

Compared with FSTI1M50T-H and FSB50550, STIPN1M50T-H uniquely combines op-amp-based current sensing, dual NTC interfaces, and interlocked logic in a 1 A footprint - delivering full protection and signal conditioning in one device, reducing component count and validation effort for sub-100 W motor drives.

FAQ

What is the maximum recommended PWM frequency for STIPN1M50T-H?

The datasheet specifies a recommended operating condition of up to 25 kHz PWM frequency under case temperature ≤100 °C. This limit balances switching losses, thermal rise, and gate drive capability; exceeding it risks thermal runaway due to insufficient heat dissipation in the NDIP-26L package's 22 °C/W junction-to-ambient resistance.

How does the T/SD/OD pin function in shutdown mode?

When pulled low (≤0.8 V), T/SD/OD forces immediate tri-state of all three half-bridges. As an output, it sinks current when overtemperature or overcurrent is detected via the internal comparator or NTC network - enabling direct connection to MCU GPIO for interrupt-driven fault handling without external logic.

Can the integrated op-amp be used for voltage sensing instead of current sensing?

Yes - the op-amp is uncommitted and supports rail-to-rail input/output. With appropriate external resistive dividers and feedback network, it can condition DC bus voltage or phase voltage signals. Its 8–12 MHz GBWP and 2.5–3.8 V/µs slew rate support accurate sampling up to ~100 kHz, suitable for overvoltage protection or sensorless commutation algorithms.

Is external bootstrap diode required when using STIPN1M50T-H?

No - the module integrates internal bootstrap diodes for all three phases (U/V/W), eliminating the need for external diodes. This reduces component count and layout complexity, while ensuring matched forward voltage drop and thermal tracking across phases - critical for balanced high-side gate charging in compact motor modules.
