† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

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 of TPS9110 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.
