General Description

The MAX5062/MAX5063/MAX5064 high-frequency,

125V half-bridge, n-channel MOSFET drivers drive high-

and low-side MOSFETs in high-voltage applications.

These drivers are independently controlled and their

35ns typical propagation delay, from input to output, are

matched to within 3ns (typ). The high-voltage operation

with very low and matched propagation delay between

drivers, and high source/sink current capabilities in a

thermally enhanced package make these devices suit-

able for the high-power, high-frequency telecom power

converters. The 125V maximum input voltage range pro-

vides plenty of margin over the 100V input transient

requirement of telecom standards. A reliable on-chip

bootstrap diode connected between V

and BST elimi-

nates the need for an external discrete diode.

The MAX5062A/C and the MAX5063A/C offer both nonin-

verting drivers (see the Selector Guide). The

MAX5062B/D and the MAX5063B/D offer a noninverting

high-side driver and an inverting low-side driver. The

MAX5064A/B offer two inputs per driver that can be

either inverting or noninverting. The MAX5062A/B/C/D

and the MAX5064A feature CMOS (V

/ 2) logic inputs.

The MAX5063A/B/C/D and the MAX5064B feature TTL

logic inputs. The MAX5064A/B include a break-before-

make adjustment input that sets the dead time between

drivers from 16ns to 95ns. The drivers are available in the

industry-standard 8-pin SO footprint and pin configura-

tion, and a thermally enhanced 8-pin SO and 12-pin

(4mm x 4mm) thin QFN packages. All devices operate

over the -40°C to +125°C automotive temperature range.
