description

The TPS9110 incorporates a complete power supply system for a cellular subscriber terminal that uses battery

packs with three or four NiMH/NiCd cells or a single lithium-ion cell. The device includes three low-dropout linear

regulators rated for 3.3 V or 3 V at 100 mA each, a charge-pump driver, and logic that includes a 250-ms reset,

on/off control, and processor interface. Regulators A and B and the charge-pump driver have separate enables

allowing circuitry to be powered up or down as necessary to conserve battery power. Regulators VL, VA, and

VB, and the charge pump driver are active as soon as UVLO and OTP are valid and ON is toggled low.

The TPS9110 operates over a free-air temperature range of –40°C to 85°C and is supplied in a 28-pin TSSOP

package.
