TPA626 Bidirectional Current and Power Monitor

The TPA626 from 3PEAK is a bidirectional current and power monitor designed for accurate power monitoring in modern digital and industrial systems. It supports high- and low-side sensing across a bus voltage range of 0 V to 36 V and operates from a 2.7 V to 5.5 V power supply. A built-in 16-bit SAR ADC enables precision current, voltage, and power measurements, and the device supports alarm functions for fault detection. With configurable averaging and 16 programmable I²C addresses, the TPA626 is ideal for monitoring multiple rails or loads. This compact, high-resolution monitor is well-suited for use in power management, telecom systems, computing infrastructure, and test equipment where insight into energy flow is critical.
