175V/2A, High-Speed,
Half-Bridge MOSFET Drivers
General Description
The MAX15012/MAX15013 high-frequency, 175V half-
bridge, n-channel MOSFET drivers drive high- and low-
side MOSFETs in high-voltage applications. These
drivers are independently controlled and their 35ns typ-
ical propagation delay, from input to output, are
matched to within 2ns (typ). The high-voltage operation
with very low and matched propagation delay between
drivers, and high source/sink current capabilities make
these devices suitable for the high-power, high-fre-
quency telecom power converters. A reliable on-chip
bootstrap diode connected between V
DD
and BST
eliminates the need for an external discrete diode.
The MAX15012A/C and MAX15013A/C offer both nonin-
verting drivers (see the
Selector Guide).
The
MAX15012B/D and MAX15013B/D offer a noninverting
high-side driver and an inverting low-side driver. The
MAX15012A/B/C/D feature CMOS (V
DD
/2) logic inputs.
The MAX15013A/B/C/D feature TTL logic inputs. The
drivers are available in the industry-standard 8-pin SO
footprint and pin configuration and a thermally
enhanced 8-pin SO package. All devices operate over
the -40°C to +125°C automotive temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1:
Package thermal resistances were obtained using the method described in JEDEC specification JE5D51-7, using a four-
layer board. For detailed information on package thermal considerations, see www.maxim-ic.com/thermal-tutorial.
