PA1611S
Description
PA1611S is a fully integrated IC with built-in MOS and Hall-based sensor for single-phase BLDC motor driver applications. It supports soft-switching square-wave control mode, and features with low noise. Motor control parameters, such as softswitching slope, lead angle, etc., can be flexibly configured via GUI to achieve required efficiency and reduce noise, in order to meet different application requirements. Moreover, the chip
supports multi-segment speed control curve, protection restart configurations and FG/RD output to fulfill different input and output requirements.
Features
◼ VCC range: 3.3V ~ 16V
◼ Drive current: 450mA@85℃
◼ High level of integration with built-in MOS
and Hall-based sensor
◼ Highly sensitive Hall-based sensor
◼ Soft-switching square-wave control for singlephase motor
◼ FG and RD output
◼ SPEED and I2C modes for motor speed
regulation
◼ Built-in EFUSE
◼ Configurable multi-segment output curve
◼ Forward and reverse direction control
◼ Soft-on feature protects the motor from abrupt
startup and reduces current shock and noise
◼ Support protection features, including current
limiting protection (CLP), over-current
protection (OCP), temperature sensor detect
(TSD), motor lock protection (MLP), etc.
