STMicroelectronics TSC1214 Power Monitor Analog Front End (AFE)
STMicroelectronics TSC1214 Power Monitor Analog Front End (AFE) is designed to monitor a low-voltage power supply. The digital current, voltage, and temperature monitoring TSC1214 utilizes a double monitoring path for current based on a 14-bit ADC and voltage or temperature based on an 11-bit ADC. The AFE is programmable via the I²C interface.
The STMicro TSC1214 is available in a plastic MiniSO8 package and operates in the -40°C to +85°C ambient temperature range.
