MAX15018/MAX15019 19-4146 Rev 1 9/08 125V/3A, High-Speed, Half-Bridge MOSFET Drivers General Description Features The MAX15018A/MAX15018B/MAX15019A/MAX15019B HIP2100IB/HIP2101IB Pin Compatible (MAX15018A/MAX15019A) high-frequency, 125V half-bridge, n-channel MOSFET drivers drive high- and low-side MOSFETs in high-volt- Up to 125V V Operation IN age applications. These drivers are independently con- 8V to 12.6V V Input Supply Range DD trolled, and their 35ns (typ) propagation delay, from input 3A Peak Source and Sink Current to output, are matched to within 2ns (typ). The high-volt- age operation with very low and matched propagation 35ns Propagation Delay delay between drivers, and high source-/sink-current Guaranteed 8ns or Less Propagation Delay capabilities in a thermally enhanced package make Matching Between High- and Low-Side Drivers these devices suitable for high-power, high-frequency Both Noninverting/Noninverting and telecom power converters. The 125V maximum input Noninverting/Inverting Logic-Input Versions voltage provides plenty of margin over the 100V input Available transient requirement of telecom standards. A reliable on-chip bootstrap diode connected between V and DD Up to 15V Logic Inputs, Independent of V DD BST eliminates the need for an external discrete diode.

The MAX15018B/MAX15019B offer a noninverting Available in CMOS (V /2) or TTL Logic-Level DD high-side driver and an inverting low-side driver (see the Inputs with Hysteresis Selector Guide.) The MAX15018 feature CMOS (V /2) DD Available in a Space-Saving, Thermally Enhanced logic inputs. The MAX15019 feature TTL-logic inputs. 8-Pin SO-EP Package The drivers are available in the industry-standard 8-pin SO footprint and pin configuration with a thermally Ordering Information enhanced 8-pin SO package. All devices operate over the -40C to +125C automotive temperature range.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
