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.

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. Digital bus interface is flexible from I²C/SMbus 1 MHz data rate to 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 regarding the voltage, current, power and temperature. 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.

The TSC200, TSC201 and TSC202 are high-side current sense amplifiers which deliver an analog voltage output. They can sense current via a shunt resistor over a wide range of common-mode voltages, from -16 to +80 V, whatever the supply voltage is. They are available with an amplification gain of 20 V/V for TSC200, 50 V/V for TSC201, and 100 V/V for TSC202. The TSC200, TSC201 and TSC202 integrate an open-drain comparator with output latch function and an internal 0.6 V voltage reference connected to its input. The external resistor divider can then set the switching threshold. These devices fully operate over the broad supply voltage range of 2.7 to 18 V and over the automotive temperature range of -40 to +125 °C.
