12-Channel/8-Channel, Flash-Configurable System
Managers with Nonvolatile Fault Registers
Set r74h[4:3] to a value other than ‘00’ to select autoretry
mode (see Table 20). In this configuration, the device
shuts down after a critical fault event then restarts
following a configurable delay. Use r74h[2:0] to select an
autoretry delay from 20ms to 2s. See Table 20 for more
information on setting the autoretry delay.
When fault information is stored in flash (see the Critical
Faults section) and autoretry mode is selected, set an
autoretry delay greater than the time required for the
storing operation. When fault information is stored in
flash and latch-on-fault mode is chosen, toggle EN or
reset the software enable bit only after the completion of
the storing operation. When saving information about the
failed lines only, ensure a delay of at least 150ms before
the restart procedure. Otherwise, ensure a minimum
280ms timeout, to ensure that ADC conversions are com-
pleted and values are stored correctly in flash.
Programmable Ouputs
(EN_OUT1–EN_OUT12)
The MAX16065 includes twelve programmable out-
puts, and the MAX16066 includes eight programmable
outputs. These outputs are capable of connecting to
either the enable (EN) inputs of a DC-DC or LDO power
supply, or to drive the gate of an n-channel MOSFET in
charge-pump mode. Selectable output configurations
include: active-low or active-high, open drain or push-
pull. EN_OUT1–EN_OUT8 can act as charge-pump
outputs, EN_OUT9–EN_OUT12 can be configured as
general-purpose inputs or general-purpose outputs. Use
registers r30h to r33h to configure outputs. See Table
21 for detailed information on configuring EN_OUT1–
EN_OUT12.
In charge-pump configuration, EN_OUT1–EN_OUT8 act
as high-voltage charge-pump outputs to drive up to eight
external n-channel MOSFETs. During sequencing, an EN_
OUT_ output set to the charge-pump configuration outputs
11V relative to GND. See the Sequencing section for more
detailed information on power-supply sequencing.
In open-drain output configuration, connect an exter-
nal pullup resistor from the output to an external voltage
up to 5.5V (EN_OUT9–EN_OUT12) or 14V (EN_OUT1–
EN_OUT8). Choose the pullup resistor depending on the
number of devices connected to the open-drain output
and the allowable current consumption. The open-drain
output configuration allows wire-ORed connection.
In push-pull configuration, the MAX16065/MAX16066’s
programmable outputs are referenced to V DBP .
