概述

The TPA6290 is a 3-channel high-side current and bus voltage monitor with I²C/SMBUS compatible interfaces. The device monitors both shunt voltage and bus power supply voltage, and also has programmable conversion time and averaging modes. The device also provides several critical and warning alarms to detect multiple outof-programmable ranges for each channel.

The TPA6290 can sense a shunt voltage drop on the bus, with bus voltage ranging up to 36 V. The device is powered by a 2.7-V to 5.5-V power supply. The TPA6290 has an operating temperature range of −40°C to +125°C. The I2C and SMBUS-compatible interface has four programmable addresses.
