Layout Consideration
SRT is a precise current source. When developing the
layout for the application, be careful to minimize board
capacitance and leakage currents around this pin.
Traces connected to SRT should be kept as short as
possible. Traces carrying high-speed digital signals
and traces with large voltage potentials should be rout-
ed as far from SRT as possible. Leakage current and
stray capacitance (e.g., a scope probe) at this pin
could cause errors in the reset timeout period. When
evaluating these parts, use clean prototype boards to
ensure accurate reset periods.
