PMIC Module - CYALKIT-A18
CYALKIT-A18 is the PMIC module for the power block of an automotive application with CYT4B Series MCU. The PMIC
Module implements the Cypress PMIC S6BP501A and is optimized for power supply of CYT4B Series MCU. 1.1 V output to
supply to VCCD of CYT4B Series MCU needs external schottky barrier diode (SBD), output capacitor and constant load cur-
rent no less than 20 mA.
