Overview

The TPS61381QEVM-126 operates over a wide back up battery voltage range of 0V to 12V and main battery (VBAT port) voltage range of 0V-40V to achieve a bi-directional operation. The EVM supports an output up to 7.5A load at 3.6V BUB and 6.2V output in boost mode, and supports 50-100mA charging current in charger mode. The TPS61381QEVM-126 can support output voltage regulation accuracy better than 2.5% in boost mode and support better than 1% voltage accuracy in charger mode. The device functions are adjustable using I2C interface.

Features
  • Integrated 20mΩ high-side MOSFET and 6mΩ ISO FET to support true disconnection
  • I2C programmable CC, CV charger with integrated charging strategy
  • Auto detection on system voltage and automatic transition into boost mode when car battery malfunction occurs
  • Fault or operation status indication by STATUS pin and I2C
  • Backup battery State-of-Health(SOH) detection
  • 20μA quiescent current in standby mode
  • < 1μA shutdown current
  • < 1μA leakage current for pins connected to the back up battery (at Tj up to 60°C)
  • Frequency: 400kHz for automotive applications
  • Programmable spread spectrum for optimizing EMI
  • 3mm × 4mm 25-pin package with wettable flank
AC/DC & DC/DC converters (integrated FET)
