  • Page 3: Introduction

    Introduction The TLV840EVM is an evaluation module (EVM) for the TLV840 voltage supervisor. The TLV840EVM can be used with any TLV840 device variant but note that if using the push-pull variants (TLV840PLXX or TLV840PHXX), the shunt on J2 must be removed as push-pull devices do not use a pull-up resistor so R1 must be disconnected.

    EVM Setup and Operation www.ti.com EVM Setup and Operation This section describes the functionality and operation of the TLV840EVM. The user must read the TLV840 datasheet for electrical characteristics of the device. Input Power (V The VDD supply is connected through the J1 header on board. Both pins of jumper J1 are connected together so power can be applied to either pin.

The other device variants provide different output topolgies and can be used on this EVM. Note: if using a TLV840 device variant with push-pull output topology, the pull-up resistor must be disconnected by leaving jumper J2 open.
