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).
