Currently, the voltage detectors/voltage supervisors use either footprint option A or
footprint option D.

Using the TC53C or TC54VC, no passive components would be required and the
device V
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
D1 pad.
The TC52 is a dual-channel voltage detector. This means that the device has a V
and a V
Locations R2A and R2E should be installed with 47 kΩ resistors.
Detect voltage 2 (V
typically used to indicate a low-power situation, with V
system. Typically, a 0.1 µF capacitor would be on the V
location).
Power supply filtering may be required, so a 0.1 µF capacitor is suggested in the C4
location.
