12-Channel/8-Channel, Flash-Configurable System

Managers with Nonvolatile Fault Registers

MAX16065/MAX16066

General Description

The MAX16065/MAX16066 flash-configurable system

managers monitor and sequence multiple system volt-

ages. The MAX16065/MAX16066 can also accurately

monitor (±2.5%) one current channel using a dedicated

high-side current-sense amplifier. The MAX16065 man-

ages up to twelve system voltages simultaneously, and

the MAX16066 manages up to eight supply voltages.

These devices integrate a selectable differential or sin-

gle-ended analog-to-digital converter (ADC) and con-

figurable outputs for sequencing power supplies. Device

configuration information, including overvoltage and

undervoltage limits, timing settings, and the sequenc-

ing order is stored in nonvolatile flash memory. During a

fault condition, fault flags and channel voltages can be

automatically stored in the nonvolatile flash memory for

later read-back.

The internal 1% accurate 10-bit ADC measures each

input and compares the result to one overvoltage, one

undervoltage, and one early warning limit that can be

configured as either undervoltage or overvoltage. A fault

signal asserts when a monitored voltage falls outside the

set limits. Up to three independent fault output signals

are configurable to assert under various fault conditions.

Because the MAX16065/MAX16066 support a power-

supply voltage of up to 14V, they can be powered

directly from the 12V intermediate bus in many systems.

The integrated sequencer provides precise control over

the power-up and power-down order of up to twelve

(MAX16065) or up to eight (MAX16066) power supplies.

Eight outputs (EN_OUT1–EN_OUT8) are configurable

with charge-pump outputs to directly drive external

n-channel MOSFETs.

The MAX16065/MAX16066 include eight/six programma-

ble general-purpose inputs/outputs (GPIO_s). GPIO_s

are flash configurable as dedicated fault outputs, as a

watchdog input or output, or as a manual reset.

The MAX16065/MAX16066 feature nonvolatile fault mem-

ory for recording information during system shutdown

events. The fault logger records a failure in the internal

flash and sets a lock bit protecting the stored fault data

from accidental erasure. An SMBus™ or a JTAG serial

interface configures the MAX16065/MAX16066. The

MAX16065 is available in a 48-pin, 7mm x 7mm, TQFN

package, and the MAX16066 is available in a 40-pin,

6mm x 6mm, TQFN package. Both devices are fully

specified from -40NC to +85NC.
