The Texas Instruments TPS1HC30EVM is an evaluation module that is used to demonstrate and showcase all
of the features of the underlying TPS1HC30-Q1 automotive high side switch. This evaluation board provides
a seamless way to connect a power supply to the input of the TPS1HC30-Q1, connect a load to the output
channel, and switch on and off the device using the control pins of the chip itself. An onboard 3.3-V LDO is
included on the EVM to simplify controlling signals to the TPS1HC30-Q1 and easily assert and deassert logic
signals by the use of a set of external hardware jumpers. Additionally, this EVM includes BoosterPack headers
allowing the user to easily connect the TPS1HC30-Q1 high side switch to an underlying microcontroller and write
software to control and configure the device.
Features of the TPS1HC30EVM include:
• Standalone operation with standard bench equipment or easy pairing with external microcontroller through
BoosterPack headers
• Onboard TPL0102-100 digital potentiometer to allow for a programmable current limit through I2C
• Potentiometer for SNS and ILIM resistors, allowing for easy configuration of external resistance values
• Onboard 3.3-V LDO, allowing for control signals to be manipulated by set of jumpers
• Four-layer 2-oz board layout and copper area for thermal performance
• Optional footprints for input TVS diodes to extend transient protection of the device
