Internal Analog Voltage Bypass. Bypass ABP to GND with a 1µF ceramic capacitor.
ABP powers the internal circuitry of the MAX16046A/MAX16048A. Do not use ABP
to power any external circuitry.
Power-Supply Input. Bypass V
Internal Digital Voltage Bypass. Bypass DBP to GND with a 1µF ceramic capacitor.
DBP supplies power to the EEPROM memory, to the internal logic circuitry, and to
the internal charge pumps when the programmable outputs are configured as
charge pumps. All push-pull outputs are referenced to DBP. Do not use DBP to
power any external circuitry.
General-Purpose Input/Output 1. Configure GPIO1 as a logic input, a return sense
line for closed-loop tracking, an open-drain/push-pull fault output, or an open-
drain/push-pull output port. Use the EEPROM to configure GPIO1. See the General-
Purpose Inputs/Outputs section.
General-Purpose Input/Output 2. GPIO2 is configurable as a logic input, a return
sense line for closed-loop tracking, an open-drain/push-pull fault output, or an
open-drain/push-pull output port. GPIO2 is also configurable as a dedicated
Inputs/Outputs section.
General-Purpose Input/Output 3. GPIO3 is configurable as a logic input, a return
sense line for closed-loop tracking, an open-drain/push-pull fault output, or an
open-drain/push-pull output port. GPIO3 is also configurable as a dedicated
Inputs/Outputs section.
General-Purpose Input/Output 4. GPIO4 is configurable as a logic input, a return
sense line for closed-loop tracking, an open-drain/push-pull fault output, or an
open-drain/push-pull output port. GPIO4 is also configurable as an active-low
manual reset,
Inputs/Outputs section.
Output. EN_OUT1–EN_OUT6 are configurable with active-high/active-low logic and
with an open-drain or push-pull configuration. Program the EEPROM to configure
EN_OUT1–EN_OUT6 as a charge-pump output 5V greater than the monitored input
voltage (V
tracking.
Output. Configure EN_OUT_ with active-low/active-high logic and with an open-
drain or push-pull configuration.
Output. Configure EN_OUT_ with active-low/active-high logic and with an open-
drain or push-pull configuration.
Exposed Pad. Internally connected to GND. Connect to GND. EP also functions as a
heatsink to maximize thermal dissipation. Do not use as the main ground
connection.
MON_
input. Use the EEPROM to configure GPIO2. See the General-Purpose
input. Use the EEPROM to configure GPIO3. See the General-Purpose
+ 5V). EN_OUT1–EN_OUT4 can also be used for closed-loop
. Use the EEPROM to configure GPIO4. See the General-Purpose
