The TPS3842-Q1 is an automotive 42V input voltage supervisor with 850nA IDD and 1.5% accuracy, and a fast detection time. The TPS3842-Q1 can be connected directly to 12V battery for continuous monitoring of undervoltage (UV) conditions or overvoltage (OV) conditions. The TPS3842-Q1 comes in a small DRL package for size constrained applications. Built-in hysteresis on the SENSE pin prevents false reset signals when monitoring a supply voltage rail. 1%, 5%, and 10% hysteresis voltage options are available to offer design flexibility to support voltage transients.

SENSE is decoupled from VDD and can monitor higher and lower voltages than VDD. Fixed threshold variants provide accurate low-Iq voltage monitoring. Adjustable threshold variants offer flexible undervoltage threshold setting with external resistors. TPS3842-Q1 offers capacitor programmable de-glitch on the SENSE with the CTS pin and capacitor programmable reset delay timing with the CTR pin.
