3 Description

The TPS37-Q1 is a 65 V input voltage detector with 1 μA IDD, 1% accuracy, and with a fast 10 μs detection

time. This device can be connected directly to 2 V / 24 V automotive battery system for continuous monitoring of over (OV) and under (UV) voltage conditions; with its internal resistor divider, it offers the smallest total solution size. Wide hysteresis voltage options are available to ignore cold crank, start-stop and various car battery voltage transients. Built-in hysteresis on the SENSE pins prevents false reset signals when monitoring a supply voltage rail.

The separate VDD and SENSE pins allow redundancy sought by high-reliability automotive systems and SENSE can monitor higher and lower voltages than VDD. Optional use of external resistors are supported by the high impedance input of the SENSE pins. CTSx and CTRx pins allow delay adjustability on the rising and falling edges of the RESET signals. Also, CTSx functions as a debouncer by ignoring voltage glitches on the monitored voltage rails; CTRx operates as a manual reset (MR) that can be used to force a system reset.

TPS37-Q1 is available in WSON or SOT-23 package. The WSON package has wettable flanks allowing the facilitation for Automatic Optical Inspection (AOI) and low resolution X-ray inspection. The central pad is non-conductive to increase the creepage between VDD and GND per guidelines in IEC60664.
