MOTOROLA ANALOG IC DEVICE DATA
The MC33128 is a power management controller specifically designed for
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.
Also included are protective system shutdown features consisting of a
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.
