DESCRIPTION

The LM25101A/B/C High Voltage Gate Drivers are

designed to drive both the high-side and the low-side

N-Channel MOSFETs in a synchronous buck or a

half-bridge configuration. The “A” versions provide a

full 3A of gate drive while the “B” and “C” versions

provide 2A and 1A respectively. The outputs are

independently controlled with TTL input thresholds.

An integrated high voltage diode is provided to

charge the high-side gate drive bootstrap capacitor. A

robust level shifter operates at high speed while

consuming low power and providing clean level

transitions from the control logic to the high-side gate

driver. Under-voltage lockout is provided on both the

low-side and the high-side power rails. These devices

are available in the standard SOIC-8 pin, SO Power

Pad-8, WSON-8 (4 mm x 4 mm), WSON-10 (4 mm x

4 mm), and MSOP Power Pad-8 packages.

•

Excellent propagation delay matching (3 ns

typical)

•

Supply rail under-voltage lockout

Low power consumption

Pin compatible with HIP2100/HIP2101

TYPICAL APPLICATIONS

•

Motor controlled drivers

Half and Full Bridge power converters

Synchronous buck converters

Two switch forward power converters

Forward with Active Clamp converters

48V server power

Solar DC/DC and DC/AC converters
