FUNCTION
+2V to +6V Input Voltage to power the MAX749 and external circuitry. When using an external
P-channel MOSFET, V+ must exceed the MOSFET’s gate threshold voltage.
Logic Input. When CTRL is high, a rising edge on ADJ increments an internal counter. When CTRL is
low, the counter is reset to mid-scale when ADJ is high. When ADJ is low, the counter does not
change (regardless of activity on CTRL) as long as V+ is applied.
Logic Input. When CTRL and ADJ are low, the MAX749 is shut down, but the counter is not reset.
When CTRL is low, the counter is reset to mid-scale when ADJ is high. The device is always on when
CTRL is high.
Feedback Input for output full-scale voltage selection. -V OUT(MAX) = (R FB ) x (20μA) where R FB is
connected from FB to -V OUT . The device is in regulation when V FB = 0V.
Ground
Output Driver Low. Connect to DHI when using an external P-channel MOSFET. When using an
external PNP transistor, connect a resistor R BASE from DLOW to the base of the PNP to set the maxi-
mum base-drive current.
Output Driver High. Connect to the gate of the external P-channel transistor, or to the base of the
external PNP transistor.
Current-Sense Input. The external transistor is turned off when current through the sense resistor,
R SENSE , brings CS below V+ by 140mV (typ).
