BD6510F / BD6512F / BD6513F
Multimedia ICs
Low ON resistance USB high-side switch series
BD6510F / BD6512F / BD6513F
This series of high-side switching ICs have 2-channnel MOSFET switches that have low ON resistances. These
functions are useful for USB power control. Error signals can be conveyed via a built-in error detection circuit. Also
included is a thermal shutdown circuit with a latch that can protect the output from unstable operation occurred by
repeating the ON/OFF switch of the output protection circuit.
zApplications
USB hub, Notebook PC, Desk-top PC, Power switch

Operating description
Thermal shutdown shut off the both output MOSFET and
Error flag latch
Thermal shutdown (TSD)
signals error flag is the chip temperature exceeds TTS
.
TSD function only when the CTRL is enable.
UVLO prevents the output MOSFET from turning on until
DD exceeds VUVLOH and signals error flag. After the switch
V
Under voltage lockout (UVLO)
Over current detector (OCD)
turn on, if VDD drops below VUVLOL shut off the output
MOSFET and signals error flag.
UVLO functions only when the CTRL is enable.
Over current detector shut off the output MOSFET and
signals error flag if output current exceeds ILIM
.
OCD functions only when the CTRL is enable.
Latch is released by forcing CTRL input SW OFF level or detecting UVLO.
Connect a bypass capacitor from VDD to GND, located near the IC. Recommend over 1µF.
Connect a over 100kΩ pull-up resistor from FLAG to VDD
.
