Power Management Controller

use in battery powered cellular telephone and pager applications. This

device contains all of the active functions required to interface the user to the

system electronics via a microprocessor. This integrated circuit consists of a

low dropout voltage regulator with power–up reset for MPU power, two low

dropout voltage regulators for independant powering of analog and digital

circuitry, and a negative charge pump voltage regulator for full depletion of

gallium arsenide MESFETs.

battery latch that is activated upon battery insertion, low battery voltage

shutdown, and a thermal over temperature detector. This device is available

in a 16–pin narrow body surface mount plastic package.
