Product Details

Description



Features:

Complete supervisory and sequencing solution for up to 8 supplies
8 supply fault detectors enable supervision of supplies to better than 1% accuracy
4 selectable input attenuators allow supervision:
   Supplies up to 14.4 V on VH
   Supplies up to 6 V on VP13
4 dual-function inputs, VX14
   High impedance input to supply fault detector with thresholds between 0.573 V and 1.375 V
   General-purpose logic input
8 programmable output drivers (PDO18):
   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 (PDO16 only)
Sequencing engine (SE) implements state machine control of PDO outputs:
   State changes conditional on input events
   Enables 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
Device powered by the highest of VP13, VH for improved redundancy
User EEPROM: 256 bytes
Industry-standard 2-wire bus interface (SMBus)
Guaranteed PDO low with VH, VPn = 1.2 V
32-lead 7 mm * 7 mm LQFP package
