STMicroelectronics PWD5T60TR

Overview

PWD5T60TR from STMicroelectronics is a three-phase high-density power stage integrating gate driver and six 500 V N-channel MOSFETs in VFQFPN 12×12 mm package, with R_DS(on) = 1.38 Ω, 9–20 V input supply range, and Smart ShutDown overcurrent protection. It serves as a compact motor drive solution for fans, pumps, refrigerator compressors, and home appliances.

For engineers reviewing the PWD5T60TR datasheet, PWD5T60TR pinout, PWD5T60TR application, or PWD5T60TR equivalent, key selection considerations include bootstrap diode integration, matched propagation delay across all six channels, interlocking/deadtime logic, dual UVLO (VCC & VBO), and thermal shutdown at 135 °C with 20 °C hysteresis.

Technical Context

The PWD5T60TR implements a fully integrated three-phase half-bridge architecture with independent high-side (HIN1–3) and low-side (LIN1–3) TTL/CMOS-compatible inputs, each featuring 30–40 ns input filtering and 0.9 V hysteresis. Its SmartSD comparator uses an internal 480 mV reference and 70 mV hysteresis on CIN to trigger sub-1 µs fault response.

Deadtime is internally fixed at 300 ns ±50 ns per channel and enforced via hardware interlocking; external deadtime overrides internal timing. UVLO thresholds are 9.2 V (turn-on) / 8.7 V (turn-off) for VCC and 8.7 V / 8.2 V for each VBO rail, with dedicated pull-down resistors (100 kΩ) on all logic inputs to ensure defined states during floating conditions.

FAQ

What is the maximum continuous output current per phase for PWD5T60TR?

The PWD5T60TR supports 2 A continuous drain current per MOSFET at T_CB = 100 °C, corresponding to ~1.4 A RMS per phase in typical 3-phase BLDC operation. This rating assumes proper thermal management via the EPAD and PCB copper area; actual current depends on ambient temperature, airflow, and switching frequency.

Does PWD5T60TR require external bootstrap capacitors?

Yes-external ceramic bootstrap capacitors (typically 100–220 nF X7R, 25 V) are required on BOOT1–BOOT3 pins. The integrated zero-drop diodes eliminate external bootstrap diodes, but capacitors must be placed close to each BOOT pin with low-inductance routing to sustain high-side gate drive during PWM operation.

How does the Smart ShutDown (SmartSD) function differ from standard overcurrent protection?

SmartSD decouples fault detection latency (<1 µs) from fault hold duration. Unlike conventional comparators whose response depends on external RC timing, SmartSD triggers immediate MOSFET turn-off upon CIN exceeding V_REF, while OD pin discharge/recharge controls only the restart delay-enabling both ultrafast protection and flexible recovery timing without design trade-offs.

Can PWD5T60TR operate with 3.3 V microcontroller logic levels?

Yes-the HIN, LIN, and EN inputs are fully compatible with 3.3 V TTL/CMOS logic: V_IL = 0.8–1.4 V and V_IH = 1.8–2.3 V with 0.9 V hysteresis. Internal 100 kΩ pull-down resistors ensure reliable low-state definition even with unterminated MCU outputs.
