Description

The TSC1214 is a digital current, voltage, and temperature monitoring Analog Front

End (AFE), meant to monitor a low voltage power supply. It implements a double

monitoring path for current based on a 14-bit ADC and voltage or temperature based

on an 11-bit ADC. The device is programmable through the I²C interface.

The TSC1214 comes in a plastic MiniSO8 package and can operate in the -40 °C to

+85 °C ambient temperature range.
