MAX6782–MAX6785 Hysteresis
Factory-Set Hysteresis
The MAX6782–MAX6785 have factory-set hysteresis for
ease of use and reduced external parts count. For
these devices the absolute hysteresis voltage is a per-
centage of the internally generated reference. The
amount depends on the device option. “A” devices
have 0.5% hysteresis, “B” devices have 5% hysteresis,
and “C” devices have 10% hysteresis. Table 2 presents
the threshold voltages for devices with factory-set hys-
teresis. For factory-set hysteresis, connect HADJ_ to
GND.
Externally Adjusted Hysteresis
The MAX6782–MAX6785 can also be configured for
externally adjustable hysteresis. Connect a resistive
divider from REF to HADJ_ and to GND (Figure 6) to set
the hysteresis voltage. The hysteresis adjustment range
is from 0.4V to VREF, and the voltage at HADJ_
(VHADJ_) must be set higher than Hysteresis
Adjustment Logic High (VHALH) (Figure 4b). Note that if
VHADJ_ is lower than Hysteresis Adjustment Logic Low
(VHALL), these devices switch back to the internal fac-
tory-set hysteresis (Figure 4a).
MAX6786/MAX6787/MAX6788 Adjustable
Hysteresis
The MAX6786/MAX6787/MAX6788 offer external hystere-
sis control through the resistive divider that monitors bat-
tery voltage. Figure 2 shows the connections for external
hysteresis. See
Calculating an External Hysteresis
Resistive Divider (MAX6786/MAX6787/MAX6788) section
for more information.
