概述

Description

DRV8350HRTVR is TI’s 3‑phase brushless DC motor driver with integrated six MOSFETs. It provides three independent half‑bridges to drive a BLDC or PMSM motor from a single supply, using PWM inputs for each phase. Key features include built‑in current regulation (via an external sense resistor), a bootstrap high‑side drive scheme, and comprehensive protections (undervoltage, overcurrent, overtemperature) with fault/diagnostic reporting. The device supports braking, fast‑decay/slow‑decay modes, and is suitable for compact, efficient motor control in robotics, printers, automotive or industrial applications. For exact electrical specs, pinout, and packaging details (including the HRTVR variant), refer to the TI DRV8350 datasheet.

Features

DRV8350HRTVR is a 3-phase gate-driver for external MOSFETs used in BLDC motor drive. Key features:
- Drives three half-bridges (HOx/LOx) with bootstrapped high-side operation for BLDC motors.
- Wide VS supply range up to about 55 V; logic inputs IN1–IN3 with EN_GATE for PWM control.
- Integrated dead-time control to prevent shoot-through.
- Protections: undervoltage, overcurrent, overtemperature, and overvoltage on the supply.
- Fault diagnostics with FAULT and STATUS outputs (latchable/clearable behavior in many use cases).
- Suitable for sensorless or Hall-based BLDC control with flexible control timing.
- Package: DRV8350HRTVR (Tape & Reel) in HTSSOP-type footprint.
Applications: motor drivers for fans, pumps, robotics, and other 3-phase BLDC motor systems requiring external MOSFETs.

Package

HTSSOP package (HTSSOP-20). The TVR suffix indicates Tape-and-Reel packaging.

Pinout

28 pins in an HTSSOP-28 (HRTVR) package. Function: triple half-bridge motor driver for BLDC/3-phase motors. It contains three high-side/low-side MOSFET pairs (A/B/C outputs) driven by three inputs (IN1–IN3), providing motor phase outputs (AOUT/BOUT/COUT) with current regulation and protection/diagnostics (overcurrent, undervoltage, overtemperature, faults).

Manufacturer

The DRV8350HRTVR is manufactured by Texas Instruments (TI). TI is a global American semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (ICs) and embedded processing solutions for automotive, industrial, and consumer markets.

Application

Applications of DRV8350HRTVR:
- 3-phase BLDC motor drives for robotics and automation (BLDC/servo systems)
- Consumer/industrial equipment (fans, pumps, blowers)
- HVAC cooling fans
- Power tools
- Automotive auxiliary motors (cooling fans, pumps)
