A5950

DC Motor Driver

FEATURES AND BENEFITS

DESCRIPTION

Designed for pulse-width-modulated (PWM) control of DC

motors, the A5950 is capable of peak output currents up to

±3 A and operating voltages up to 40 V.

• Overcurrent protection (OCP)

• Motor lead short-to-ground protection

• Motor lead short-to-battery protection

• Motor short protection

• Low-power standby mode

• Fault output

Inputterminalsareprovidedforuseincontrollingthespeedand

direction of a DC motor with externally applied PWM control

signals. Internal synchronous rectification control circuitry is

provided to lower power dissipation during PWM operation.

• Adjustable current limit option

• Current-to-voltage output

Internal circuit protection includes overcurrent protection,

motor lead short to ground or supply, thermal shutdown with

hysteresis, undervoltage monitoring of VBB, and crossover-

current protection.

• Synchronous rectification – high-side

• Internal UVLO

• Crossover-current protection

• Thermal warning and shutdown function

• AEC-Q100 Grade 1 qualified – K version
