Rainbow Electronics MAX5064 User Manual

General Description
The MAX5062/MAX5063/MAX5064 high-frequency, 125V half-bridge, n-channel MOSFET drivers drive high­and 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 VDDand BST elimi­nates the need for an external discrete diode.
The MAX5062A/C and the MAX5063A/C offer both nonin­verting drivers (see the Selector Guide). 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 (V
DD
/ 2) logic inputs. The MAX5063A/B/C/D and the MAX5064B feature TTL logic inputs. The MAX5064A/B include a break-before­make 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.
