The HV400MJ/883 is a single monolithic, non-inverting high
current driver designed to drive large capacitive loads at high
slew rates. The device is optimized for driving single or paral-
lel connected N-Channel power MOSFETs with total gate
charge from 5nC to >1000nC. It features two output stages
pinned out separately allowing independent control of the
MOSFET gate rise and fall times. The current sourcing output
stage is an NPN capable of 6A. An SCR provides over 30A of
current sinking. The HV400MJ/883 achieves rise and fall
times of 54ns and 16ns respectively driving a 10,000pF load.
Special features are included in this part to provide a simple,
high speed gate drive circuit for power MOSFETs. The
HV400MJ/883 requires no quiescent supply current, how-
ever, the input current is approximately 15mA while in the
high state. With the internal current steering diodes (Pin 7)
and an external capacitor, both the timing and MOSFET gate
power come from the same pulse transformer; no special
external supply is required for high side switches. No high
voltage diode is required to charge the bootstrap capacitor.
The HV400MJ/883 in combination with the MOSFET and
pulse transformer makes an isolated power switch building
block for applications such as high side switches, secondary
side regulation and synchronous rectification. The
HV400MJ/883 is also suitable for driving IGBTs, MCTs,
BJTs and small GTOs.
The HV400MJ/883 is a type of buffer; it does not have input
logic level switching threshold voltages. This single stage
design achieves propagation delays of 20ns. The output
NPN begins to source current when the voltage on Pin 2 is
approximately 2V more positive than the voltage at Pin 8.
The output SCR switches on when the input Pin 2 is 1V
more negative than the voltage at Pins 3/6. Due to the use of
the SCR for current sinking, once the output switches low,
the input must not go high again until all the internal SCR
charge has dissipated, 0.5µs - 1.5µs later.
