3 Description
The LM5100A/B/C and LM5101A/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
floating high-side driver is capable of operating with
supply voltages up to 100 V. The A versions provide
a full 3-A of gate drive, while the B and C versions
provide 2 A and 1 A, respectively. The outputs are
independently controlled with CMOS input thresholds
(LM5100A/B/C) or TTL input thresholds
(LM5101A/B/C).
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. Undervoltage 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
PowerPAD-8 pin, and the WSON-10 pin packages.
The LM5100C and LM5101C are also available in
MSOP-PowerPAD-8 package. The LM5101A is also
available in WSON-8 pin package.
