TPS7H3014EVM-CVAL Evaluation Module (EVM)

Description

The
TPS7H3014EVM-CVAL
operation of a single
TPS7H3014-SP
(ceramic package). The board provides footprints
that can be populated with additional components to
allow for testing of customized configurations, such as
daisy-chained sequencers.

  • Page 5 Evaluation Module Overview 1.3.1 Alternate Board Configurations The TPS7H3014EVM-CVAL board provides footprints that can be populated with components for testing a "daisy-chain" configuration of 2 TPS7H3014-SP sequencers. The configuration is used to increase the number of monitored SENSEx inputs and ENx outputs that can be used for sequencing.

    1.6V ≤ VPULL_UPx ≤ 7V 2.2 Important Usage Notes The TPS7H3014EVM-CVAL board is configured so that the ENx signals are tied by a 0Ω resistor to their respective SENSEx signal. This configuration is purely for simplicity of testing device features and behavior when external voltages are not available to be sensed by the SENSEx pins.

    5. External System RESET 3.1 Default Configuration Results The following tests were performed using the TPS7H3014EVM-CVAL in the default configuration with VIN=12V and PULL_UP1=PULL_UP2=1.8V or 3.3V (indicated by voltage seen on the ENx, PWRGD, SEQ_DONE, and FAULT signals). All UP and DOWN sequences were initiated by raising or lowering VIN, as shown in the first two tests, unless stated otherwise.
