The MAX15018A/MAX15018B/MAX15019A/MAX15019B 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 (typ) 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 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 drivers. The MAX15018B/MAX15019B offer a noninverting high-side driver and an inverting low-side driver (see the Selector Guide in the full data sheet). 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.
