5.0 A Throttle Control H-bridge
enhanced package. It is 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.
up to 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 11 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. The disable inputs are provided to force the H-
bridge outputs to tri-state (high-impedance off-state).
