General Description
The TC429 is a high-speed, single output, CMOS-level
translator and driver. Designed specifically to drive
highly capacitive power MOSFET gates, the TC429
features a 2.5 output impedance and 6A peak output
current drive.
A 2500 pF capacitive load will be driven to 18V in
25 nsec. The rapid switching times with large
capacitive loads minimize MOSFET switching power
losses.
A TTL/CMOS input logic level is translated into an
output voltage swing that equals the supply voltage and
will swing to within 25 mV of ground or V
DD
. Input volt-
age swing may equal the supply voltage. Logic input
current is under 10 µA, making direct interface to
CMOS/bipolar switch-mode power supply controllers
easy. Input “speed-up” capacitors are not required.
The CMOS design minimizes quiescent power supply
current. With a logic ‘1’ input, power supply current is
5 mA maximum and decreases to 0.5 mA for logic ‘0’
inputs.
For dual output MOSFET drivers, see the TC426/
TC427/TC428 (DS21415), TC4426/TC4427/TC4428
(DS21422) and TC4426A/TC4427A/TC4428A
(DS21423) data sheets.
For non-inverting applications, or applications requiring
latch-up protection, see the TC4420/TC4429
(DS21419) data sheet.
