The SY24657/B (SY24657 and SY24657B) uses a 16-bit ADC (Analog to Digital Converter) along with a dedicated analog front-end to enable precise monitoring of current, voltage, and power of a separate rail. 16 addresses, configurable using two dedicated pins, enable multiple devices connected with application processor on the same I2C or SMBUS-compatible interface.

An integrated power accumulator can be used for average power calculations. Programmable calibration value, conversion times, and averaging when combined with an internal multiplier enable direct readouts of current in amperes and power in watts.

A flexible interrupt generation scheme will enable alerting the host when the voltage, current or power levels on the monitored rail are below or above the configured thresholds.

The SY24657B is configured to start in power-down mode.

The SY24657/B can be used to monitor bus voltages that can vary from 0V to 36V, independent of the supply voltage.

The SY24657/B is available in the CSP1.39mm×1.68mm -12 package.
