  • DRV101  -  Fixed 24kHz oscillator. Wider supply range. 2.3A output drive instead of 1.5A or 3A.
  • DRV102  -  High side power switch. Fixed 24kHz oscillator. Wider supply range. 2.7A output drive instead of 1.5A or 3A.

Description

The DRV103 is a low-side DMOS power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, motors, and positioners. 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 DRV103 can be set to provide a strong initial closure, automatically switching to a "soft" hold mode for power savings. A resistor, analog voltage, or Digital-to-Analog (D/A) converter can control the duty cycle. An output OK flag indicates when thermal shutdown or over current occurs.

Two packages provide a choice of output current: 1.5A (SO-8) or 3A (PowerPAD™ SO-8 with exposed metal heat sink).

The DRV103 is specified for \x9640°C to +85°C.
