1.1 Introduction

The TPS3842EVM helps design engineers evaluate the operation and performance of the TPS3842 family undervoltage monitors for possible use in the own circuit applications. This particular EVM configuration contains the TPS3842A011DRLR, an undervoltage supervisor designed to monitor an adjustable rail with the DRL package. The TPS3842 family includes adjustable capacitor pins for tying capacitors to adjust delays on both the rising and falling edges of the RESET outputs. Separately available SENSE input pins allow the redundancy sought by safety-critical and high-reliability systems. Section 3 provides schematics, a BOM, and layout information on the board. Section 2.1 describes the connectors, jumpers, and test points for the device. Section 2.2 describes the setup and operation of the EVM.

This user’s guide describes the operational use of the TPS3842EVM evaluation module (EVM) as a reference design for engineering demonstration and evaluation of the TPS3842, a low-power, high input voltage, undervoltage monitor. Included in this user’s guide are setup instructions, a schematic diagram, printed-circuit board (PCB) layout drawings, and a bill of materials for the EVM.
