FEATURES

10 supply fault detectors enabling supervision of supplies to

better than 1% accuracy

5 selectable input attenuators allow supervision:

Supplies up to 14.4 V on VH

Supplies up to 6 V on VP1-4

5 dual function inputs VX1-5:

High impedance input to supply fault detector with

thresholds between 0.573 V and 1.375 V

General-purpose logic input

Device powered by the highest of VP1–4, VH

2.048 V reference (±0.25%) on REFOUT pin

12-bit ADC for read-back of all supervised voltages

Reference input, REFIN—2 input options:

Driven directly from REFOUT

More accurate external reference for improved ADC

performance

6 voltage output 8-bit DACs (0.300 V to 1.551 V)

Internal temperature sensor

Remote temperature sensor

10 programmable output drivers (PDO1-10)

Open collector with external pull-up

Push-pull output, driven to VDDCAP or VPn

Open collector with weak pull-up to VDDCAP or VPn

Internally charge pumped high drive for use with external

N-FET (PDO1–6 only)

Sequencing Engine (SE) implements State Machine control

of PDO outputs:

State changes conditional on input events

Can enable complex control of boards

Power up and power down sequence control

Fault event handling

Interrupt generation on warnings

Watchdog function can be integrated in SE

Program software control of sequencing through SMBus

User EEPROM—256 Bytes

Industry standard 2-wire bus interface (SMBus)

Guaranteed PDO low with VH, VPn = 1.2V

40-lead LFCSP and 48-lead TQFP packages

APPLICATIONS
