125V/2A, High-Speed,
Half-Bridge MOSFET Drivers
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
DD
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
DD
/ 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.
