System and Method for a Battery and Test Circuit

摘要

According to an embodiment, a system includes a switching regulator and an electrochemical storage test circuit. The switching regulator is coupled to a power supply input and configured to supply a regulated voltage to a regulated supply terminal that is configured to be coupled to a device. The electrochemical storage test circuit is configured to be coupled to an electrochemical storage unit. The electrochemical storage test circuit includes a bidirectional switch with a first switch terminal coupled to the regulated supply terminal, a second switch terminal configured to be coupled to the electrochemical storage unit, and a switch control terminal. The electrochemical storage test circuit also includes a built-in self-test (BIST) circuit configured to be coupled to the electrochemical storage unit and to the switch control terminal.
