General Description

The MAX15012/MAX15013 high-frequency, 175V 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-

ical 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 make

these devices suitable for the high-power, high-fre-

quency telecom power converters. A reliable on-chip

bootstrap diode connected between V

and BST

eliminates the need for an external discrete diode.

The MAX15012A/C and MAX15013A/C offer both nonin-

verting drivers (see the Selector Guide). The

MAX15012B/D and MAX15013B/D offer a noninverting

high-side driver and an inverting low-side driver. The

MAX15012A/B/C/D feature CMOS (V

/2) logic inputs.

The MAX15013A/B/C/D feature TTL logic inputs. The

drivers are available in the industry-standard 8-pin SO

footprint and pin configuration and a thermally

enhanced 8-pin SO package. All devices operate over

the -40°C to +125°C automotive temperature range.

175V/2A, High-Speed, Half-Bridge MOSFET Drivers The MAX15012/MAX15013 are 175V/2A high-speed, half-bridge MOSFET drivers that operate from a supply voltage of +8V to +12.6V. The drivers are intended to drive a high-side switch without any isolation device like an optocoupler or drive transformer. The high-side driver is controlled by a TTL/CMOS logic signal referenced to ground. The 2A source and sink drive capability is achieved by using low R DS_ON , p- and n-channel driver output stages.

MAX15012/MAX15013 175V/2A, High-Speed, Half-Bridge MOSFET Drivers Minimum Input Pulse Width The MAX15012/MAX15013 use a single-shot level-shifter architecture to achieve low propagation delay. Typical level shifter architecture causes a minimum (high or low) pulse width (tDmin) at the output that may be higher than the logic-input pulse width.

MAX15012/MAX15013 175V/2A, High-Speed, Half-Bridge MOSFET Drivers Applications Information Supply Bypassing and Grounding Pay extra attention to bypassing and grounding the MAX15012/MAX15013. Peak supply and output currents may exceed 4A when both drivers are driving large external capacitive loads in-phase. Supply drops and ground shifts create forms of negative feedback for inverters and may degrade the delay and transition times.
