DESCRIPTION

The DRV595 is a high-efficiency, high-current power driver ideal for driving a wide variety of loads in systems

powered from 4.5V to 26V. PWM operation and low output stage on-resistance significantly decrease power

dissipation in the amplifier.

The DRV595 advanced oscillator/PLL circuit employs multiple switching frequency options; this is achieved

together with a Master/Slave option, making it possible to synchronize multiple devices.

The DRV595 is fully protected against faults with short-circuit, thermal, over-voltage, and under-voltage

protection. Faults are reported back to the processor to prevent devices from being damaged during overload

conditions.
