User's Guide SLVU686B – March 2012 – Revised June 2012 DRV110 and DRV120 Evaluation Modules (EVM) This document describes the features and operation of the DRV110 and DRV120 Evaluation Modules (EVM). This EVM is a Texas Instruments HV EVM providing the key components necessary for evaluation of a DRV110 or a DRV120 integrated circuit (IC). This document shows how to power the DRV110 and DRV120 ICs with the EVM and contains the schematic, a printed circuit board (PCB), and a bill of materials. Figure 1.

Background www.ti.com 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.

Operation www.ti.com 4 Operation 4.1 Safety WARNING This EVM does not provide any kind of safety isolation, therefore, all voltages on the EVM are considered hazardous. Use isolated equipment when working with the EVM. Minimize the risk of fire hazard by replacing fuse F1 only with fuse T0.5AL250V. Power supply connectors of the EVM, P1 and P2, are protected by fuses F1 and F2, respectively.
