Installation and Operation
2.5
VOLTAGE SUPERVISOR/VOLTAGE DETECTOR CIRCUITS
Currently, the voltage detectors/voltage supervisors use either footprint option A or
footprint option D.
2.5.1
Option D Circuit
Using the TC53C or TC54VC, no passive components would be required and the
device V OUT could be monitored on the D1 pad.
Using the TC53N or TC54VN, an external pull-up resistor is required. This resistor
would be installed in the R2A location and the device V OUT could be monitored on the
D1 pad.
The TC52 is a dual-channel voltage detector. This means that the device has a V OUT1
and a V OUT2 output. Both outputs are open-drain and require a pull-up resistor.
Locations R2A and R2E should be installed with 47 k Ω resistors.
Detect voltage 2 (V OUT2 ) is lower than detect voltage 1 (V OUT1 ). Therefore, V OUT1 is
typically used to indicate a low-power situation, with V OUT2 being used to reset the
system. Typically, a 0.1 μF capacitor would be on the V OUT2 pin (installed in the C5E
location).
Power supply filtering may be required, so a 0.1 μF capacitor is suggested in the C4
location.
