Internal Analog Voltage Regulator Output. Bypass ABP to GND with a 1µF ceramic
capacitor. ABP powers the internal circuitry of the MAX16046/MAX16048 and
supplies power to the internal charge pumps when the programmable outputs are
configured as charge pumps. Do not use ABP to power any external circuitry.
Power-Supply Input. Bypass V
Internal Digital Voltage Regulator Output. Bypass DBP to GND with a 1µF ceramic
capacitor. DBP supplies power to the EEPROM memory and the internal logic
circuitry. 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 TTL 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 TTL 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 MARGINUP
input. Use the EEPROM to configure GPIO2. See the General-Purpose
Inputs/Outputs section.
General-Purpose Input/Output 3. GPIO3 is configurable as a TTL 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 MARGINDN
input. Use the EEPROM to configure GPIO3. See the General-Purpose
Inputs/Outputs section.
General-Purpose Input/Output 4. GPIO4 is configurable as a TTL 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, MR. Use the EEPROM to configure GPIO4. See the General-Purpose
Inputs/Outputs section.
Output. EN_OUT1–EN_OUT6 are configurable with active-high/active-low logic and
with open-drain or push-pull configurations. Program the EEPROM to configure
EN_OUT_ with a charge-pump output 5V greater than the monitored input voltage
(V
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.
