Texas Instruments TPS2640EVM eFuse Evaluation Module (EVM)

Texas Instruments TPS2640EVM eFuse Evaluation Module (EVM) allows reference circuit evaluation of the TPS2640 devices. The Texas Instruments TPS2640 is compact 4.2V to 42V, 2.23A industrial eFuses with integrated back-to-back FETs, programmable under voltage, overvoltage, and reverse-polarity features. It also has overcurrent, in-rush current protection, and output current monitoring features.

Features

4.2V to 42V input operating voltage range
0.2A to 2.23A jumper-programmable current limit
Reverse polarity protection up to –42V
Programmable input UVLO
Selectable overload fault response (auto-retry, latch, and circuit breaker)

Programmable input overvoltage protection (OVP) cut off
Programmable V_OUT slew rate control
Load current monitor output with 1.5V/A
Optional onboard transient protection devices like input TVS and output Schottky diodes
Onboard reset switch and fault indicators

Required Equipment

Power Supplies
- One adjustable power supply: 0V to 42V output, 0A to 3A output current limit
Meters
- One DMM minimum needed and may require more if simultaneous measurements are required

Oscilloscope
- A DPO2024, or equivalent with three 10x voltage probes and one DC current probe
Loads
- One resistive load which can tolerate up to 3A DC load at 24V

Applications

HMI power protection in factory automation
Fire safety systems

Electronic thermostats and video doorbells
