The Evaluation Kit features the 33926, which is a 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. The 33926 is able to control inductive loads with currents 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 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.
- Over current Limiting via Internal Constant-Off-Time PWM
- Output Short Circuit Protection
- Temperature-Dependant 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
- 8V to 28V continuous operation (transient operation from 5V to 40V)
- 3V and 5V TTL / CMOS logic compatible inputs
- Over current limiting (regulation) via internal constant off time PWM
- All Inputs have an internal source/sink to define the default (floating input) states
- Sleep mode with current draw < 50μA (with inputs floating or set to match default logic states)
