Page 2: Introduction
All other trademarks are the property of their respective owners. 1 Introduction The TPS2640EVM allows reference circuit evaluation of TI's TPS2640 devices. The TPS2640 are compact 4.2- V to 42-V, 2.23-A industrial eFuses with integrated back-to-back FETs, programmable undervoltage, overvoltage, reverse-polarity, overcurrent, inrush current protection, and output current monitoring features. -
Page 3: Description
Description 2 Description The TPS2640EVM enables full evaluation of the TPS2640 devices. The EVM supports HTSOP and QFN versions of the devices on two channels (CH1 and CH2, respectively). Input power is applied at T1 (CH1) and T3 (CH2) while T2 (CH1) and T4 (CH2) provide an output connection to the load. See the schematic in... -
