DRV103H .

The DRV103H is a DMOS low-side Power Switch employs a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices. The DRV103 is also ideal for driving thermal devices such as heaters, coolers and lamps. PWM operation conserves power and reduces heat rise, resulting in higher reliability. In addition, adjustable PWM allows fine control of the power delivered to the load. DC-to-PWM output delay time and oscillator frequency are also externally adjustable. The driver can be set to provide a strong initial closure, automatically switching to a "soft" hold mode for power savings. A resistor, analogue voltage or Digital-to-analogue (D/A) converter can control the duty cycle. An output OK flag indicates when thermal shutdown or over-current occurs.
