3 Description
The TPS38-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
12 V / 24 V automotive battery system for continuous
monitoring of over (OV) or 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.
TPS38-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.
