1 Description

The TPS3860xxEVM-736 can be used to evaluate the various features of the TPS3860xx family of

supervisors. Through resistor dividers, each supervisor can be individually configured to monitor voltages

as low as 0.4 V with the EVM initially being set up for 3.3 V - 12%, 2.5 V - 6%, and 1.8 V - 7 % for

supervisors 1 through 3, respectively. The fourth supervisor (SENSE4L and SENSE4H) can be configured

for either windowed or positive and negative monitoring, with the EVM default being set as a 1.2 V ± 7%

windowed supervisor. The delays for each supervisor can also be individually set through timing

capacitors. An input and output are provided for the WDT as well as an input for the manual reset.

1.1 General Features

• Inputs provided for all four supervisors, including a negative supply input for the fourth supervisor

• Placeholders to configure supervisor 4 for positive and negative monitoring

• Watchdog timer input and output

• Manual reset input

• Replaceable timing capacitors to independently program the delay of each supervisor

1.2 Orderable Options

• TPS386000EVM-736 - 4-channel supervisor/sequencer with open-drain RESET outputs

• TPS386040EVM-736 - 4-channel supervisor/sequencer with push-pull RESET outputs
