DRV8251ADDAR | TI Texas Instruments | N-Channel H-Bridge Brushed DC Motor Driver

✅Core Electrical Parameters

Power supply voltage (VM): 4.5V ~ 48V, absolute maximum withstand voltage 50V

Peak output current: 4.1A

Total Rds(on) for upper and lower bridges: Typical 450 mΩ

PWM control frequency: 0~200kHz, supporting 1.8V/3.3V/5V MCU logic levels.

Current sampling scheme: IPROPI internal current mirror (a feature of the A series), directly outputs proportional current for stall detection and current limiting; Set the current-limiting threshold via the VREF pin.

Static sleep current: <1μA @ 24V, low-power standby mode.

Operating temperature range (TJ): -40°C ~ +150°C

Built-in protection

UVLO: Undervoltage Lockout

OCP Overcurrent Protection (Automatic Retry)
