1.3 Description

The TPSI2140Q1EVM is a four-copper layer board containing multiple test points and jumpers to fully evaluate the functionality of the device. The primary side consists of four differential drivers which deliver power and enable logic information to each of the internal MOSFETs on the secondary side. Each MOSFET on the secondary side has a dedicated full-bridge rectifier to form the local power supply. When the enable pin is brought HI, the oscillator starts and the drivers send power and a logic HI across the barrier. The avalanche robust MOSFETs and the thermal benefits of the widened pins on the 11 DWQ package enable the TPSI2140-Q1 to withstand High Potential (HiPot) screening and DC fast charger surge currents of up to 2 mA without requiring any external protection components.
