5.4.1.3 Battery Source Power Supply Design Guidelines

•The desired nominal output for the power supply is 3.8V and the maximum voltage allowed is 4.2V, hence a single 3.7V Li-Ion cell battery type is suited for supplying the power to the Telit GE863-PRO3module.

The three cells Ni/Cd or Ni/MH 3,6 V Nom. battery types or 4V PB types MUST NOT BE USED DIRECTLY since their maximum voltage can rise over the absolute maximum voltage for the GE863-PRO3and damage it.

NOTE: DON'T USE any Ni-Cd, Ni-MH, and Pb battery types directly connected with GE863-PRO3. Their use can lead to overvoltage on the GE863-PRO3and damage it. USE ONLY Li-Ion battery types.

•A Bypass low ESR capacitor of adequate capacity must be provided in order to cut the current absorption peaks, a 100μF tantalum capacitor is usually suited.

•Make sure the low ESR capacitor (usually a tantalum one) is rated at least 10V.

•A protection diode should be inserted close to the power input, in order to save the GE863-PRO3from power polarity inversion. Otherwise the battery connector should be done in a way to avoid polarity inversions when connecting the battery.
