They Can Also Be Operated at Nominal Values Without External Components. Protection – Thermal Shutdown – Undervoltage Lockout (UVLO) Optional STATUS Output Operating Temperature Range: –40ºC to +125ºC 8-Pin and 14-Pin TSSOP Package Options 2 Applications Electromechanical Drivers: Solenoids, Valves, Relays, Contactors, Switchgear, Pneumatics White Goods, Solar, Transportation, Smart Grid, Power Distribution 3 Description The DRV110 device is a PWM current controller for solenoids. The device is designed to regulate the current with a well-controlled waveform to reduce power dissipation. The solenoid current is ramped up fast to ensure opening of the valve or relay. Af...
