GENERAL DESCRIPTION
Support for +5V, +3.3V, +12V, and –12V supplies is provided and includes programmable current limit, voltage supervision, fault reporting, and circuit breaker functions which provide fault isolation.FEATURES
● Supports two completely independent PCI slots: - Compliant to PCI v2.3 and PCI-X 1.0b power control requirements - Provides all major power control functions for two independent PCI-X 2.0 slots● Five voltage supplies supported: +12V, -12V, +5V, +3.3V, and +3.3VAUX - Integrated gate driver circuits, current sense, and power MOSFETs for 3.3VAUX, +12V, and –12V - High-side +5V and +3.3V gate driver circuits for external N-Channel MOSFETs
● Overcurrent protection with adjustable timeout eliminates false tripping of circuit breakers
● Dual-level, dual-speed overcurrent detection circuitry for quick fault response without nuisance tripping
● Slot power control with “Power-is-Good” and Fault status reporting - Via software over an SMBus interface or - Via dedicated...
