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 V
CC
supply (+12V), the PWRON input is inhibited
from turning on the switches, and the latch is held in the
Reset state until the V
CC
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.
