PWM Driver IC
Overview
The LV8829LF is a PWM-type driver IC designed for 3-phase brushless motors. It enables the rotational speed to be
controlled by inputting an external PWM pulse signal and varying the duty factor. The IC incorporates a latch-type
constraint protection circuit.
Features
• IO max = 1.5A (built-in output Tr)
• Speed control and synchronous rectification using direct PWM input (supports 3.3V inputs)
• 1-Hall FG output
• Latch type constraint protection circuit (the latch is released by S/S and F/R.)
• Forward/reverse switching circuit, Hall bias pin
• Power save circuit (Power save in stop mode)
• Current limiter circuit, Low-voltage protection circuit, Overheat protection circuit
• Charge pump circuit, 5V regulator output.
• Start/stop circuit (short brake when motor is to be stopped)
