FRDM-33926ESEVM

FRDM-33926ESEVM is an evaluation kit that features the 33926, which is a monolithic H-bridge power IC designed primarily for automotive electronic throttle control but applies to any low-voltage DC servo motor control application within the current and voltage limits stated in this specification. The 33926 can control inductive loads with currents up to 5.0A 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 6.5A ±1.5A output loads can be pulse-width modulated (PWM’ed) at frequencies up to 20KHz supported with FRDM-KL25Z.

• 8V to 28V continuous operation (transient operation from 5V to 40V)
• 3.0V and 5.0V TTL / CMOS logic compatible inputs
• 225mohm maximum RDS(ON) at 150°C (each H-bridge MOSFET)
• Overcurrent limiting (regulation) via internal constant-off-time PWM
• Output short circuit protection (short to VPWR or ground)
• 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 <lt/> 50µA (with inputs floating or set to match default logic states)
