NXP MC33926PNB Motor Driver/Controller Half Bridge 8V to 28V Supply 5 A/2 Outputs QFN-32

The MC33926PNB is a SMARTMOS monolithic H-bridge Power IC, designed primarily for automotive electronic throttle control, but is applicable to any low-voltage DC servo motor control application within the current and voltage limits stated in this specification. It is able to control inductive loads with currents up to 5A peak. RMS current capability is subject to the degree of heat sinking provided to the device package. Internal peak-current limiting (regulation) is activated at load currents above 1.5A ±6.5A. Output loads can be pulse width modulated at frequencies up to 20kHz. A load current feedback feature provides a proportional (0.24% of the load current) current output suitable for monitoring by a microcontrollers A/D input. A Status Flag output reports under voltage, over current and over temperature fault conditions. Two independent inputs provide polarity control of two half-bridge totem-pole outputs.

• 5 to 28V Continuous operation
• 225mR Maximum RDS(on) at 150°C (each H-Bridge MOSFET)
• 3V and 5V TTL/CMOS logic compatible inputs
• Output short-circuit protection
• Temperature dependent current limit threshold reduction
• All Inputs have an internal source/sink to define default (floating input) states
• <50µA Sleep mode with current draw (with inputs floating or set to match default logic states)
