Power-Supply Decoupling
To achieve the best results when using the DS2070W,
decouple the power supply with a 0.1μF capacitor. Use
a high-quality, ceramic surface-mount capacitor if pos-
sible. Surface-mount components minimize lead induc-
tance, which improves performance, while ceramic
capacitors have adequately high frequency response
for decoupling applications.
Using the Open-Drain RST Output
The RST output is open drain, and therefore requires a
pullup resistor to realize a high logic output level. Pullup
resistor values between 1k ? and 10k ? are typical.
Battery Charging/Lifetime
The DS2070W charges an ML battery to maximum
capacity in approximately 96 hours of operation when
V CC is greater than V TP . Once the battery is charged,
its lifetime depends primarily on the V CC duty cycle.
The DS2070W can maintain data from a single, initial
charge for up to 3 years. Once recharged, this deep-
discharge cycle can be repeated up to 20 times, pro-
ducing a worst-case service life of 60 years. More

sured on the package body surface.
typical duty cycles are of shorter duration, enabling the
DS2070W to be charged hundreds of times, therefore
extending the service life well beyond 60 years.
Recommended Cleaning Procedures
The DS2070W may be cleaned using aqueous-based
cleaning solutions. No special precautions are needed
when cleaning boards containing a DS2070W module.
Removal of the topside label violates the environmen-
tal integrity of the package and voids the warranty of
the product.
