REF
1.25V reference voltage output (MAX780A and MAX780C only). Make no connection to
this pin for MAX780B.)

BVPP
Switched output that provides 0V, 5V, or 12V to the V
PP
pins of slot B.
21
17
AVPP
Switched output that provides 0V, 5V, or 12V to the V
PP
pins of slot A.

VCCIN
+5V power input
23

VPPIN
+12V power input. VPPIN can have 0V or 5V applied as long as VCCIN = 5V.

GND
Ground
MAX780A/B/C
Pin-strap input that selects edge-triggered register or direct digital inputs. Tying C2 to
VCCIN makes the logic inputs edge triggered; inputs to pins 4-11 are clocked in on the
rising edge of
WR
. Tying C2 to GND allows control signals to be directly applied to the
logic inputs on pins 4-11. Connect to GND for MAX780C.
Pin-strap input that selects one of two logic decode modes for the digital inputs. See Tables 1-3.
Logic-level power-ready output that stays low as long as BVPP is greater than 11.05V
(MAX780A and MAX780C only). Make no connection to this pin for MAX780B.
Logic-level power-ready output that stays low as long as AVPP is greater than 11.05V
(MAX780A and MAX780C only). Make no connection to this pin for MAX780B.
Logic input that shuts the MAX780 down to a low supply-current state when brought
low. Asserting
SHDN
forces ADRV3, BDRV3, ADRV5, BDRV5, REF,
AGPI
, and
BGPI
low. All V
PP
inputs and outputs are functional for either state of
SHDN
. Program AVPP
and BVPP to 0V for lowest power consumption.
Write pulse input. When C2 is tied to VCCIN, a rising edge on
WR
clocks in the V
CC
and V
PP
enables. When C2 is tied to GND, inputs to
WR
have no effect. Connect to
GND for MAX780C.

Open-drain gate driver outputs that control the MOSFETs that switch the V
CC
pin of slot
