SOT23−5
CASE 527AH
NCP51100
The NCP51100 2 A gate driver is designed to drive an N−Channel
enhancement−mode MOSFET in low −side switching applications by
providing high peak current pulses during the short switching
intervals. The driver is available with TTL input thresholds. Internal
circuitry provides an under−voltage lockout function by holding
the output LOW until the supply voltage is within the operating range.
The NCP51100 delivers fast MOSFET switching performance, which
helps maximize efficiency in high frequency power converter designs.
NCP51100 drivers incorporate MillerDrivet architecture for the final
output stage. This bipolar−MOSFET combination provides high peak
current during the Miller plateau stage of the MOSFET
turn−on / turn−off process to minimize switching loss, while
providing rail−to−rail voltage swing and reverse current capability.
The NCP51100 is available in industry standard, 5−pin, SOT23.
