The DRV120 device is a PWM current driver for solenoids. The device is designed to regulate the current with a well-controlled waveform to guarantee activation and to reduce power dissipation at the same time. The solenoid current is ramped up fast to ensure opening of the valve or relay. After the initial ramping, solenoid current is kept at peak value to ensure the correct operation, after which it is reduced to a lower hold level in order to avoid thermal problems and reduce power dissipation.
The peak current duration is set with an external capacitor. The current ramp peak and hold levels, as well as PWM frequency, can independently be set with external resistors. External setting resistors can also be omitted, if the default values for the corresponding parameters are suitable for the application.
The DRV120 can operate from an external 6-V to
28-V supply.
