Notes:

Note that there is a 100k

Ω pull-down resistor on CS.

4. Below 0°C, a negative slope on Vcc will stop the oscillator during a time which may be as long as 1 second. This is not

dependent on slope and occurs with a slew rate as low as 2V/sec.

5. Some chip versions do not support “Trickle Charger” and “Switchover” features.
