Package Type
General Description
The TC53 is a low power voltage detector. Typical
supply current consumption is only 1µA at an input
voltage of 2V. The voltage detection threshold setting is
factory-programmed and guaranteed to ±2% accuracy.
Threshold settings are available over a range of 1.6V
to 6.0V. The TC53 has both complementary (CMOS)
and open drain (NMOS) output configuration options.
TC53 is the ideal voltage detector for precision
applications in which small size, low installed cost, high
accuracy and low supply current consumption are
critical.

Note 1: An additional resistor between the VIN pin and the supply voltage may alter the electrical characteristics due to the increasing values of
VDR.
2: The power consumption during power-start to output being stable (release operation) is 2µA greater than it is after that period
(completion of release operation) because of rush current in the delay circuit.
3: VT is the factory-programmed voltage detection threshold.
