TPS1HA08x Evaluation Module
ADVANCE INFORMATION
1 Introduction
Texas Instruments TPS1HA08x evaluation module contains a TPS1HA08x integrated circuit (IC),
supporting single-channel high-side driver applications. The purpose of this EVM is to facilitate evaluation
of the TPS1HA08x for resistive, capacitive, and inductive loads.
1.1 Descriptions
The Texas Instruments TPS1HA08x EVM helps designers evaluate the operation and performance of the
TPS1HA08x.
The TPS1HA08x is a fully-protected high-side switch, with an integrated NMOS power FET, and charge
pump. Full diagnostics and high-accuracy current sense features enable intelligent control of the load.
The device diagnostic reporting has two versions to support both digital status output and analog current
sense report. The diagnostics can be disabled for multiplexing the sense pin between different devices.
1.2 Applications
The EVM is used in the following applications:
• High-side relay drivers
• High-side power switch for submodule power supply
• Bulb driver
• General resistive, inductive, and capacitive loads
• Replace electromechanical relays and fuses
1.3 Features
The EVM supports the following features:
• Single-channel high-side power switch, tested according to AECQ100-12
• Operating voltage 3 to 36 V
• Operating junction temperature: –40ºC to 150ºC
• Microcontroller input control: 3.3-V and 5-V logic compatible
• High-accuracy current sense
– Analog current sense as a ratio of the load current
• Protection:
– Reverse battery protection with external resistor
– Short-circuit protection
– Overvoltage protection
– Thermal shutdown and thermal swing with self-recovery
– ESD protection
• Diagnostic:
– On and off state output open or short to battery detection
– Overload and short-to-ground detection and power limiting
– Thermal shutdown and thermal swing diagnostic
– Version A, B, or E: Shutdown on current limit
– Version C or D: Constant current output on current limit
– Diagnostic enable function for multiplexing of MCU analog or digital port
