TLV840EVM Voltage Supervisor User Guide

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. If using TLV840EVM with the active-high variant (TLV840PHXX), the active-low
RESET label on the EVM board and throughout this user guide becomes active-high RESET. The TLV840
has a supply voltage range of 0.7 V to 6 V, and offers input connections for all device input and output
pins. Test points are provided to give the user access to an extra ground connection if needed for
oscilloscope or multimeter measurements.
