The MAX15018A/MAX15018B/MAX15019A/MAX15019B
high-frequency, 125V half-bridge, n-channel MOSFET
drivers drive high- and low-side MOSFETs in high-volt-
age applications. These drivers are independently con-
trolled, and their 35ns (typ) propagation delay, from input
to output, are matched to within 2ns (typ). The high-volt-
age operation with very low and matched propagation
delay between drivers, and high source-/sink-current
capabilities in a thermally enhanced package make
these devices suitable for high-power, high-frequency
telecom power converters. The 125V maximum input
voltage provides plenty of margin over the 100V input
transient requirement of telecom standards. A reliable
on-chip bootstrap diode connected between VDD and
BST eliminates the need for an external discrete diode.
The MAX15018A/MAX15019A both offer noninverting dri-
vers. The MAX15018B/MAX15019B offer a noninverting
high-side driver and an inverting low-side driver (see the
Selector Guide.) The MAX15018_ feature CMOS (VDD/2)
logic inputs. The MAX15019_ feature TTL-logic inputs.
The drivers are available in the industry-standard 8-pin
SO footprint and pin configuration with a thermally
enhanced 8-pin SO package. All devices operate over
the -40°C to +125°C automotive temperature range.
Applications
Telecom Power Supplies
Synchronous Buck DC-to-DC Converters
Half-Bridge, Full-Bridge, and Two-Switch
Forward Converters
Power-Supply Modules
Motor Control
