Product details

Description

The A4915 is designed for pulse width modulated (PWM) current control of 3-phase brushless DC motors.

The A4915 is capable of high current gate drive for 6 all N-channel power MOSFETs.

An internal charge pump ensures gate drive down to 7 V supply and provides limited gate drive down to 5 V.

Features

5 to 50 V supply voltage.
Latched TSD with fault output.
Drives six N-channel high current MOSFETs.
Internally controlled synchronous rectification.
Speed voltage input enables internal PWM duty cycle control of full bridge.
Center aligned PWM.
Internal UVLO and crossover current protection.
Hall switch inputs.
Adjustable dead time protection.
Low power sleep mode for battery-powered.
