DRV8376Three-Phase Integrated FET Motor Driver

1 Features

Three-phase BLDC motor driver
- Supports 48V systems
- Supports up to 100kHz PWM frequency
- Active Demagnetization to reduce power losses
- Cycle-by-cycle current limit to limit phase current
4.5V to 65V operating voltage (70V abs max)
High output current capability: 4.5A Peak
Low MOSFET on-state resistance
- 400mΩ R_DS(ON) (HS + LS) at T_A = 25°C
Reduced switching loss with 1.1V/ns slew rate and reverse recovery loss minimization technique
- Adjustable slew rate options
Low audible noise and ease of motor control with ultra-low dead time < 200ns, and propagation delay < 100ns
Low-power sleep mode
