| 发明名称 | Pulse width modulation controller | ||
| 摘要 | Disclosed herein is a Pulse Width Modulation (PWM) controller. The PWM controller includes a plurality of Field Effect Transistors (FETs) and an FET driver. A comparator compares a current flowing through the FETs with an overcurrent reference value, and microcomputer controls a motor and a circuit protection function, and turns off the FET driver when the current flowing through the FETs is greater than the overcurrent reference value as a result of comparison by the comparator. | ||

| 主权项 | 1. A Pulse Width Modulation (PWM) controller, comprising: a plurality of Field Effect Transistors (FETs) and an FET driver; a comparator configured to compare a current flowing through the FETs with an overcurrent reference value; a microcomputer configured to control a motor and perform a circuit protection function for the PWM controller; and a switch configured to cut off a connection between the microcomputer and the FET driver when the current flowing through the FETs is greater than the overcurrent reference value as a result of comparison by the comparator. | ||
