• Manufacturer Part Number: MAX6302
• Description: +5V / Low-Power uP Supervisory Circuits with Adjustable Reset/Watchdog
• Manufacturer: Maxim

SRT and SWT are precision current sources. When
developing the layout for the application, be careful to
minimize board capacitance and leakage currents
around these pins. Traces connected to these pins
should be kept as short as possible. Traces carrying
high-speed digital signals and traces with large voltage
potentials should be routed as far from these pins as
possible. Leakage currents and stray capacitance (e.g.,
a scope probe) at these pins could cause errors in the
reset and/or watchdog timeout period. When evaluating
these parts, use clean prototype boards to ensure accu-
rate reset and watchdog timeout periods.
RESET IN is a high-impedance input which is typically
driven by a high-impedance resistor-divider network
(e.g., 1MΩ to 10MΩ). Minimize coupling to transient
signals by keeping the connections to this input short.
Any DC leakage current at RESET IN (e.g., a scope
probe) causes errors in the programmed reset thresh-
old. Note that sensitive pins are located on the GND
side of the device, away from the digital I/O, to simplify
board layout.
