TC643 Datasheet Integrated Fan / Motor Driver

Manufacturer: Microchip Technology

Overview: TC643 INTEGRATED FAN / MOTOR DRIVER.

General Description

The TC643 is a switchmode brushless DC fan/motor speed driver with diagnostic circuits.

External ponents are kept to a minimum by integrating the power transistor on chip.

Any logic-level signal can be used to drive the on-chip Power Driver.

Key Features

  • s Integrates Current Limited Power Driver and Diagnostic/Monitoring Circuits in a Single IC s Works with Standard DC Brushless Fans/Motors s Supports Efficient PWM Drive with Logic-Level Input s Supply Range 2.7V to 5.5V s Motor Voltage Independent of TC643 Supply Voltage; Supports 3V-15V Fans! s Logic-Level Output Provides RPM Data s Optimized For Use as a Microcontroller Peripheral s Eliminates Discrete Components and Analog Circuit Design Effort s Internal Thermal Shutdown For Fail-safe Oper.
