EEPROM-Programmable, Hex/Quad,
Power-Supply Sequencers/Supervisors
Detailed Description
The MAX6872/MAX6873 EEPROM-configurable, multi-
voltage supply sequencers/supervisors monitor several
voltage-detector inputs and four general-purpose logic
inputs, and feature programmable outputs for highly
configurable, power-supply sequencing applications.
The MAX6872 features six voltage-detector inputs and
eight programmable outputs, while the MAX6873 fea-
tures four voltage-detector inputs and five programma-
ble outputs. Manual reset and margin disable inputs
simplify board-level testing during the manufacturing
process. The MAX6872/MAX6873 feature an accurate
internal 1.25V reference.
All voltage detectors provide two configurable thresh-
olds for undervoltage/overvoltage or dual undervoltage
detection. One high-voltage input (IN1) provides detec-
tor threshold voltages from +1.25V to +7.625V in 25mV
increments or +2.5V to +13.2V in 50mV increments.
A bipolar input (IN2) provides detector threshold volt-
ages from ±1.25V to ±7.625V in 25mV increments, or
±2.5V to ±15.25V in 50mV increments. Positive inputs
(IN3 –IN6) provide detector threshold voltages from
+0.5V to +3.05V in 10mV increments, or +1.0V to +5.5V
in 20mV increments.
The host controller communicates with the MAX6872/
MAX6873s’ internal 4kb user EEPROM, configuration
EEPROM, configuration registers, and fault registers
through an SMBus/I 2 C-compatible serial interface (see
Figure 1).
Programmable output options include active-high,
active-low, open-drain, weak pullup, push-pull, and
charge pump. Select the charge-pump output feature
to drive n-channel FETs for power-supply sequencing
(see the Applications Information section). The outputs
swing between 0 and (V ABP + 5V) when configured for
charge-pump operation.
