1 Introduction
The TLV841EVM is an evaluation module (EVM) for the TLV841 voltage supervisor. Refer to
datasheet
to understand the device features supported by different variants. The TLV841EVM can be used with any
TLV841 device variant, TLV841M, TLV841C, and TLV841S. The TLV841EVM comes pre-populated with
TLV841SADL01YBHR. If users need a different option, the existing device must be removed from the board
and replaced. The EVM board is designed to support all possible options by changing jumper configuration.
The TLV841EVM also can accommodate push-pull variants (TLV841xxPLxx or TLV841xxPHxx). If a push-pull
variant is placed onto the TLV841EVM, the shunt on J1 must be removed as push-pull devices do not use a
pull-up resistor. Therefore, R1 on the TLV841EVM must be disconnected. Please also note if using TLV841EVM
with the active-high variant (TLV841xxPHxx), the active-low RESET label on the EVM board and throughout this
User Guide becomes active-high RESET. Active low RESET output with open-drain and push-pull topologies
have a supply voltage range of 0.7 V to 5.5 V. For active high push-pull outputs (PH output topology), the
supply voltage range is 1 V to 5.5 V. The TLV841EVM includes the TLV841S device (TLV841xxDLxx) and the
EVM offers connections for all device input and output pins. Test points are provided to give the user additional
access, if needed, for oscilloscope or multi-meter measurements.
