Detailed Description

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 RDS_ON p-

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.
