Figure 1. Timing Characteristics for Noninverting and Inverting Logic Inputs
The MAX5062/MAX5063/MAX5064 are 125V/2A high-
speed, half-bridge MOSFET drivers that operate from a
supply voltage of +8V to +12.6V. The drivers are
intended to drive a high-side switch without any isola-
tion device like an optocoupler or drive transformer.
The high-side driver is controlled by a TTL/CMOS logic
signal referenced to ground. The 2A source and sink
drive capability is achieved by using low R
and n-channel driver output stages. The BiCMOS
process allows extremely fast rise/fall times and low

propagation delays. The typical propagation delay from
the logic-input signal to the drive output is 35ns with a
matched propagation delay of 3ns typical. Matching
these propagation delays is as important as the
absolute value of the delay itself. The high 125V input
voltage range allows plenty of margin above the 100V
transient specification per telecom standards.
The MAX5064 is available in a thermally enhanced
TQFN package, which can dissipate up to 1.95W (at
+70°C) and allow up to 1MHz switching frequency
while driving 100nC combined gate-charge MOSFETs.
