STMicroelectronics PWD5F60

Overview

PWD5F60 from STMicroelectronics is a high-voltage power system-in-package integrating two dual half-bridge N-channel MOSFETs (600 V BVDSS, 1.38 Ω RDS(ON)) with embedded gate drivers, bootstrap diodes, uncommitted comparators, and adjustable dead-time control. It operates across 10–20 V VCC and −40 °C to 125 °C, enabling compact full-bridge motor drive in industrial fans, cooking hoods, and factory automation.

For engineers reviewing the PWD5F60 datasheet, PWD5F60 pinout, PWD5F60 application, or PWD5F60 equivalent, this device supports dual independent half-bridge operation with UVLO on both high-side and low-side sections, 3.3–15 V logic-compatible inputs, internal bootstrap diodes, and two open-drain comparator outputs for overcurrent/overtemperature protection.

Technical Context

The PWD5F60 implements two independent gate driver channels, each driving a half-bridge pair using integrated high-side and low-side N-MOSFETs. Each channel features separate VCCx and GNDx supply domains, dedicated BOOTx pins, and independently configurable dead time via external resistor-to-GND on DTx pins.

Its functional architecture includes two uncommitted rail-to-rail comparators (CP±1/2 inputs, CPOUT1/2 open-drain outputs), internal pull-down resistors on all logic inputs (INx, PWMx, SDx), and patented integrated bootstrap structures replacing external fast-recovery diodes-enabling reliable high-side gate drive without external components under normal commutation.

FAQ

What is the maximum continuous drain current per MOSFET in the PWD5F60?

The PWD5F60 supports 3.5 A DC drain current per MOSFET at TCB = 25 °C (case bottom temperature), derating to 2 A at TCB = 100 °C. This rating assumes proper thermal design with the VFQFPN package's exposed pads soldered to ≥4 thermal vias per pad on a 2s2p FR4 board per JESD51-5/7.

Can the PWD5F60 drive a full-bridge configuration without external bootstrap diodes?

Yes-the PWD5F60 integrates a patented bootstrap structure that replaces external HV fast-recovery diodes. It uses synchronized low-side driver signals to activate an internal DMOS-diode chain, enabling reliable high-side gate charging. An external diode is only needed if boot capacitor recharge is required during sustained high-side conduction.

How does the UVLO protection function across the two half-bridge channels?

Each half-bridge has independent UVLO monitoring on its VCCx and BOOTx supplies. If VCC1 drops below 8.0 V, only half-bridge 1 disables; half-bridge 2 remains operational. Similarly, BOOT2 UVLO (threshold 7.3–8.7 V) disables only high-side MOSFETs in channel 2-ensuring partial functionality during localized supply faults.

What is the purpose of the reserved pins (e.g., pins 36, 39, NC) on the PWD5F60?

Pins 36 and 39 are marked "reserved" and internally unconnected (NC); they must remain unconnected on the PCB. Pin 19 and 44 are also NC. These pins exist for future silicon revisions or test purposes and have no electrical function-connecting them risks latch-up or undefined behavior per ST's DS12543 Rev 1 guidance.
