LF2110B / LF2113B
High-Side / Low-Side Gate Driver
Features
Drives two N-channel MOSFETs or IGBTs in
high-side / low side configuration
Description
The LF2110B and LF2113B are high voltage, high-speed
MOSFET and IGBT drivers with independent high-side and
low-side outputs. An integrated floating supply enables
the high-side driver to operate up to 500V for the LF2110B
and up to 600V for the LF2113B. Matched maximum
propagation delays of 10ns for the LF2110B and 20ns for
the LF2113B allows high frequency operation.
High-side operation up to 600V
2.5A source and sink typical output currents
Outputs tolerant to negative transients
Wide gate driver supply voltage range: 10V to 20V
Wide logic input supply voltage range: 3.3V to 20V
Wide logic supply offset voltage range: -5V to 5V
15 ns (typical) rise / 13 ns (typical) fall times with
1000 pF load
105 ns (typical) turn-on / 94 ns (typical) turn-off
delay times
Cycle-by-cycle edge-triggered shutdown circuitry
Under Voltage Lockout (UVLO) for high and low side
drivers
Logic inputs for both LF2110B and LF2113B are
compatible with standard CMOS levels (as low as 3.3V)
while the driver outputs feature high pulse current buffers
designed to minimize driver cross-conduction.
Offered in a 16-lead SOIC package, the LF2110B and
LF2113B operate over an extended temperature range of
-40 oC to +125 oC.
Extended temperature range: -40 °C to +125 °C
