SYSTEM FORCE AND SENSE SWITCHES

Each channel has switches to allow connection of the force

(FOHx) and sense (MEASVHx) lines to a central PMU for

calibration purposes. There is one set of SYS_FORCE and

SYS_SENSE pins per device. It is recommended that these

connections be made individually to each PMU channel.

TEMPERATURE SENSOR

An on-board temperature sensor monitors die temperature.

The temperature sensor is located at the center of the die. If the

temperature exceeds the factory specified value (130°C) or a

user programmable value, the device protects itself by shutting

down all channels and flagging an alarm through the latched,

open-drain TMPALM pin. Alarm status can be read back from

the alarm status register or the PMU register, where latched and

unlatched bits indicate whether an alarm has occurred and

whether the temperature has dropped below the set alarm

temperature. The shutdown temperature is set using the system

control register.
