Product overview

Description

The TSC1641 is a high precision current, voltage, power, and temperature monitoring analog front-end (AFE). It monitors current into a shunt resistor and load voltage up to 60 V in a synchronized way. The current measurement can be high-side, low-side and bidirectional.

The device integrates high precision 16-bit dual channel ADC with a programmable conversion time from 128 µs to 32.7 ms.

The digital bus interface is flexible from an I²C/SMbus 1 MHz data rate to an MIPI I3C 12.5 MHz data rate. This allows connectivity to most of the recent STM32 products.

The TSC1641 allows the assertion of several alerts on the voltage, current, power, temperature signals and thresholds can be set for each parameter in a specific register.

The TSC1641 comes in a plastic DFN10 package and can operate from -40 °C to 125 °C ambient temperature.
