TPSxHCxx-Q1 Evaluation Module
Description
The Texas Instruments' HCXX-BASE-EVM helps
designers evaluate the operation and performance of
the TPS2HC08-Q1, TPS2HC16-Q1, TPS1HC08-Q1,
TPS1HC03-Q1, and TPS1HC04-Q1 devices.
The HCXX-BASE-EVM is a hardware evaluation
module (EVM) used to evaluate the functionality
and performance of the TPSxHCxx high-side switch
devices. The evaluation module is fully equipped to
test the TPSxHCxx device family to ease the device
integration to various power system applications.
The approach to this EVM is to have a module
(daughtercard) and a base station (motherboard). The
first module in this device family and the one featured
in this User's Guide is the 2HC08-MOD-EVM. The
HCXX-BASE-EVM is designed to be used with an
attached voltage supply and output load. Features
such as overcurrent, short-to-ground, open-load, and
short-to-battery detection are enabled for use on the
evaluation module.
