DESCRIPTION
The DRV110 is a PWM current controller for solenoids. It 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. After initial ramping the 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 DRV110 limits its own supply at VIN to 15 V which is also the gate drive voltage of an external switching
device. For example, a MOSFET that is driving the solenoid load. If a lower gate drive voltage is required, an
external supply of at least 6 V can be used.
