High voltage supervisor with integrated voltage divider for low power and continuous car battery voltage monitoring. No compensation components required (only pull-up resistor), external capacitor for timing are optional to adjust voltage detection time (CTS) and release time (CTR). Sense pins are high impedance and can support external resistors if needed by the application. This device has large hysteresis voltage options to ignore cold/warm crank, start stop and other common car battery transients.
CTRx pins also work as manual reset (CTR1/MR, CTR2/MR) that can be used as a hard reset debugging mechanism or as digital mute for Telematics and Infotainment applications.
Both channels have Open Drain, Active high and Active low options. Channel 1 has Push-pull output option capable to drive an external FET/BJT.
Small WSON package with 100µm height Wettable flanks to facilitate Automatic Optical Inspection (AOI) and long pads facilitate low resolution X-Ray inspection. Central pad is non-conductive to increase the creepage between VDD and GND per guidelines in IEC 60664
