The UCCx913 family of negative voltage circuit
breakers provides complete power management,
hot-swap, and fault handling capability. The
device is referenced to the negative input voltage
and is driven through an external resistor
connected to ground, which is essentially a
current drive as opposed to the traditional voltage
drive. The on-board 10-V shunt regulator protects
the device from excess voltage and serves as a
reference for programming the maximum
allowable output sourcing current during a fault. In
the event of a constant fault, the internal timer
limits the on-time from less than 0.1% to a
maximum of 3%. The duty cycle modulates
depending on the current into the PL pin, which is
a function of the voltage across the FET, and limits
average power dissipation in the FET. The fault
level is fixed at 50 mV across the current-sense
resistor to minimize total dropout. The fault current
level is set with an external current sense resistor.
The maximum allowable sourcing current is programmed with a voltage divider from VDD to generate a fixed voltage on the IMAX pin. The current level, when the output appears as a current source, is equal to VIMAX/RSENSE. If desired, a controlled current startup can be programmed with a capacitor on the IMAX pin. When the output current is below the fault level, the output device is switched on.
When the output current exceeds the fault level, but is less than the maximum sourcing level programmed by the IMAX pin, the output remains switched on, and the fault timer starts charging CT. Once CT charges to 2.5 V, the output device is turned off and performs a retry some time later. When the output current reaches the maximum sourcing current level, the output appears as a current source, limiting the output current to the set value defined by IMAX.
Other features of the UCCx913 family include undervoltage lockout, and 8-pin small outline (SOIC) and dual-in-line (DIP) packages.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltages are with respect to VSS (the most negative voltage). All currents are positive into and negative out of the specified terminal.
