1 Background
The DRV110 IC is a power-saving pulse-width modulator (PWM) controller for solenoids with an internal
supply regulator designed for a wide voltage range. The DRV120 IC provides similar load-current control
with an integrated MOSFET switch output stage allowing a wide internal supply voltage range.
The 14-pin DRV110 and DRV120 IC are labeled on the board as U1. Peripheral components required to
evaluate device features are also on the EVM. An external power supply and solenoid load (not provided
with the EVM) must be wired to connectors on the EVM and the board must be configured before use.
Various signals on the board can be accessed through test points and an output connector.
This EVM provides access to the features of the DRV110 or DRV120 ICs. Some modifications can be
made to this module to test performance at different input and output voltages, currents and frequencies.
