TMP821中文资料30V（最大值）含传感器半波单相 BLDC 栅极驱动器数据手册TI规格书

描述 Description

The TMP821 device is a two-phase half-wave motor predriver that is suited for fan motors, which has winding in push-pull configuration. It uses differential hall effect sensors for commutation signals for two of the switches in power circuit. The device has a very small pin count, making it very simple to use.

特性 Features

• Built-In Lock Detection and Rotational Speed Sensing Mechanisms
• Compact 8-Pin Package Reduces Number of External Components Required
• Automatic Restart When Motor Lock Is Undone
• Hall Amplifier Inputs Have Hysteresis
