tor between RESET and V

holds RESET high when

falls below 1V (Figure 4). Open-drain RESET ver-

sions are not recommended for applications requiring

valid logic for V down to zero.

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.
