USB Dual Port Power Supply Controller
The ISL6119 is a USB dual port power controller, fully
independent overcurrent (OC) fault protection IC.
Operational over the +2.5V to +5.5V range, this device
features internal current monitoring, accurate current
limiting, integrated power switches and current limited
delay to latch-off for system protection.
The ISL6119 current sense and limiting circuitry sets the current
limit to a nominal 1A, making this device well suited for the USB
port power management application. The ISL6119 provides OC
fault notification, accurate current limiting and a consistent
timed latch-off thus isolating and protecting the voltage bus in
the presence of an OC event or short circuit. The 12ms time to
latch-off is independent of the adjoining switch’s electrical or
thermal condition and the OC response time is inversely related
to the OC magnitude.
Each ISL6119 incorporates in a single 8 lead SOIC
package two 80mΩ N-channel MOSFET power switches
for power control. Each switch is driven by a constant
current source giving a controlled ramp up of the output
voltage. This provides a soft start turn-on eliminating bus
voltage drooping caused by inrush current while charging
heavy load capacitances. Independent enabling inputs and
fault reporting outputs for each channel are compatible with
3V and 5V logic to allow external control and monitoring.
The ISL6119 undervoltage lockout feature prevents turn-on
of the outputs unless the correct ENABLE state and VIN >
2.5V are present. During initial turn-on the ISL6119
prevents fault reporting by blanking the fault signal. Rising
and falling outputs are current limited voltage ramps so that
both the inrush current and voltage slew rate are limited,
independent of load. This reduces supply droop due to
surge and eliminates the need for external EMI filters.
During operation, once an OC condition is detected the
appropriate output is current limited for 12ms to allow
transient conditions to pass. If still in current limit after the
current limit period has elapsed, the output is then latched
off and the fault is reported by pulling the corresponding
FAULT low. The FAULT signal is latched low until reset by
the ENABLE signal being de-asserted at which time the
FAULT signal will clear.
