5.0 A Throttle Control H-Bridge
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.
5.0 A peak. RMS current capability is subject to the degree of
heatsinking provided to the device package. Internal peak-current
limiting (regulation) is activated at load currents above 6.5 A ± 1.5 A.
Output loads can be pulse width modulated (PWM’ed) at frequencies
up to 20 kHz. A load current feedback feature provides a proportional
(0.24% of the load current) current output suitable for monitoring by a
microcontroller’s A/D input. A Status Flag output reports under-
voltage, over-current, and over-temperature fault conditions.
totem-pole outputs. Two independent disable inputs are provided to
force the H-Bridge outputs to tri-state (high-impedance off-state). An
inverted input changes the IN1 and IN2 inputs to LOW = true logic.
Features
• 5.0 to 28 V continuous operation (transient operation from 5.0 to
• 225 mΩ maximum R
• 3.0 V and 5.0 V TTL / CMOS logic compatible inputs
• Over-current limiting (Regulation) via an internal constant-off-time
• Output short-circuit protection (short to VPWR or ground)
• Temperature-dependent current-limit threshold reduction
• All Inputs have an internal source/sink to define the default (floating input) states
• Sleep mode with current draw < 50 µA (with inputs floating or set to match default logic states)
• Pb-free packaging designated by suffix code PNB
The 33926 is a monolithic H-Bridge Power IC designed primarily
The 33926 is able to control inductive loads with currents up to
