 Description |
|
|
The HIP1011B, the third product in the HIP1011 family, is an electronic circuit breaker that monitors, reports and protects circuits from excessive load currents. As a pin-for-pin drop-in alternative offering similar functionality to the widely used HIP1011, the HIP1011B is compatible with CompactPCI peripheral boards and PCI Hot Plug systems where voltage "health" monitoring and reporting are centralized by the system controller IC. The HIP1011B does not monitor nor respond to under voltage conditions thus making control of a wide range of voltages possible.
The HIP1011B creates a small and simple yet complete power control solution to control the four independent supplies (+5V, +3.3V, +12V, and -12V) found in PCI and CompactPCI systems. For the +12V and -12V supplies, overcurrent protection is provided internally with integrated current sensing FET switches. For the +5V and +3.3V supplies, overcurrent protection is provided by sensing the voltage across the external current-sense resistors. The PWRON input controls the state of both internal and external switches. During an overcurrent condition on any output, all MOSFETs are latched-off and a LOW (0V) is asserted on the FLTN output. The FLTN latch is cleared when the PWRON input is toggled low again. During initial power-up of the main VCC supply (+12V), the PWRON input is inhibited from turning on the switches, and the latch is held in the Reset state until the VCC input is greater than 10V.
User programmability of the overcurrent threshold, response time and turn-on slew rate is provided. A resistor connected to the OCSET pin programs the overcurrent thresholds. A capacitor may be added to the FLTN pin to adjust the fault reporting and power-supply latch-off response times after an over-current event. Capacitors connected to the gate pins determine the turn-on rate. |
