nal, causing the battery pack to need at least three ter-
minals: BATT+, BATT,- and THERM. The MAX781’s
TEMP pin connects to the battery pack’s thermistor
(Figure 6). Without the battery pack installed, R8 pulls
the MAX781’s TEMP pin up to 3OUT, and BATTSTAT =
1. When the battery pack is inserted, the resistive
divider formed by the thermistor and R8 pulls the TEMP
pin below 3OUT, forcing BATTSTAT = 0. Any transition
of BATTSTAT sets BATTINT. Clear BATTINT by writting
a logic 1 in bit 31 of the serial-configuration data. The
BATTSTAT comparator is disabled in low-power and
shutdown modes, and outputs a logic zero regardless
of the state of its inputs.
3VINT and 3VSTAT indicate the status of the 3OUT
output (+3.3V ±4%). 3OUT is out of regulation when
its output voltage falls below +3.1V. 3VSTAT = 0 when
3OUT is in regulation, and 3VSTAT = 1 when 3OUT is
out of regulation. A rising edge on 3VSTAT sets
3VINT; thus, 3OUT going out of regulation sets 3VINT.
