Datasheet
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.
