TPS371K-Q1 is an automotive supervisor for voltage monitoring with an integrated buffer for 400V and 800V DC-link voltage measurements. The TPS371K-Q1 eliminates large resistor ladders with the integrated high voltage ladder. This devices SENSE pin can be directly connected to 400V or 800V automotive battery systems and DC-Link for continuous monitoring of overvoltage (OV), undervoltage (UV), and low undervoltage (LUV) conditions. The TPS371K-Q1 offers CTS for programmable glitch rejection for noisy environments.
The TPS371K-Q1 has a integrated high-speed buffer VSENSE for supply voltage measurements. The buffer has a low output impedance which can directly drive ADC inputs. VSENSE is a scaled down voltage of the SENSE pin input.
The combination of voltage supervisor and integrated buffer allows for the smallest signal chain size for direct monitoring of 400V and 800V systems. This combination also allows for redundant digital and analog always on voltage fault monitoring.
The TPS371K-Q1 is available in a 12.8mm × 7.4mm SOIC 15-pin package. TPS371K-Q1 operates over -40°C to +125°C TA.
