MAX5062, MAX5062A：125V/2A, High-Speed, Half-Bridge MOSFET Drivers

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 suitable for the high-power, high-frequency telecom power converters. The 125V maximum input voltage range 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 MAX5062A/C and the MAX5063A/C offer both noninverting drivers (see the Selector Guide of the full data sheet). 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 (VDD / 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 configuration, 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.
