3 Description
The TPS3762-Q1 is a 65V input voltage supervisor
with 4μA IDD, 0.9% accuracy, fast detection time
(5μs), and a Built-In Self-Test feature. This device can
be connected directly to 12V / 24V automotive battery
systems for continuous monitoring of overvoltage
(OV) and undervoltage (UV) conditions; with the
internal resistor divider, the TPS3762-Q1 offers the
smallest total solution size. Wide hysteresis voltage
options are available to ignore large voltage transients
and prevent false reset signals.
The separate VDD and SENSE pins allow
redundancy sought by high-reliability 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 pin. CTS
and CTR pins allow delay adjustability on the falling
and rising edges of the RESET signal. The CTS
functions as a debouncer by ignoring voltage glitches
on the monitored voltage rails.
The TPS3762-Q1 is available in a 2.9mm × 1.6mm
SOT23 8-pin package.
