LM5110
Dual 5A Compound Gate Driver with Negative Output
Voltage Capability
General Description
The LM5110 Dual Gate Driver replaces industry standard
gate drivers with improved peak output current and effi-
ciency. Each “compound” output driver stage includes MOS
and bipolar transistors operating in parallel that together sink
more than 5A peak from capacitive loads. Combining the
unique characteristics of MOS and bipolar devices reduces
drive current variation with voltage and temperature. Sepa-
rate input and output ground pins provide Negative Drive
Capability allowing the user to drive MOSFET gates with
positive and negative VGS voltages. The gate driver control
inputs are referenced to a dedicated input ground (IN_REF).
The gate driver outputs swing from V
to the output ground
V
which can be negative with respect to IN_REF. The
ability to hold MOSFET gates off with a negative VGS volt-
age reduces losses when driving low threshold voltage
MOSFETs often used as synchronous rectifiers. When driv-
ing with conventional positive only gate voltage, the IN_REF
and V
pins are connected together and referenced to a
common ground. Under-voltage lockout protection and a
shutdown input pin are also provided. The drivers can be
operated in parallel with inputs and outputs connected to
double the drive current capability. This device is available in
the SOIC-8 and the thermally-enhanced LLP-10 packages.
