TEXAS INSTRUMENTS  DRV103UG4  芯片, PWM 低边驱动器 1.5A/3A

The 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 and positioners. It 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. It 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.
