TI’s TPS37, TPS38, and TPS3760 supervisor families
support an input voltage range of 2.7 - 65 V, and have a rich feature set including:
OV, UV, and Window monitoring options:
Flexible options for monitoring undervoltage (UV) faults, overvoltage faults (OV) or both
at the same time (window monitoring).
Fixed or adjustable voltage threshold
options: Voltage thresholds can be set using an external resistor divider, or with
an internal divider built into the supervisor to limit solution size and Iq.
Threshold Hysteresis: Voltage thresholds
have built in hysteresis to help provide power supply stability. A variety of fixed
hysteresis options are available for all of TI’s wide VIN supervisors, and some
topologies allow hysteresis to be adjusted with external resistors.
Push pull and open drain output
topologies: A wide range of output topology options allow TI’s wide VIN
supervisors to integrate seamlessly into the logic of any design.
Adjustable sense delay: The sense delay
determines how long the supervisor waits to assert a reset signal after a voltage fault is
detected. This allows the supervisor to ignore glitches and known transients on the
monitored rail and provides noise immunity. This time delay can be programmed with an
external capacitor, allowing it to be tailored to meet specific power supply
requirements.
Adjustable reset delay: The reset delay
determines how long the supervisor waits to deassert a reset signal after the monitored
power rail returns to its acceptable range. This gives the rail time to stabilize after
starting up or recovering from a fault. This time delay can be programmed with an external
capacitor, allowing it to be tailored to meet specific power supply requirements.
Ultra low quiescent current (Iq): TI’s
family of wide VIN supervisors have an extremely low quiescent current (~1µA),
which means very little power is used when idle. This makes them an excellent choice to
power sensitive or battery powered applications.
Automotive qualified (-Q1) variants: All
of TI’s wide VIN supervisors are available in AEC-Q100 qualified variants
designed for automotive end equipment
