特性
- 8.0V to 28V continuous operation (transient operation from 5.0V to 40V)
- 235mΩ maximum RDS(ON) @ Tj=150°C (each H-Bridge MOSFET)
- 3.0V and 5.0V TTL / CMOS logic compatible inputs
- Over-current limiting (regulation) via internal constant-off-time PWM
- Output short-circuit protection (short to VPWR or GND)
- 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 < 50μA (each half with inputs floating or set to match default logic states)
