The 33926 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 stated in this specification.

Features

• 5.0 to 28 V continuous operation (transient operation from 5.0 to 40 V)

• 225 mΩ maximum RDS(ON) @ 150°C (each H-Bridge MOSFET)

• 3.0 V and 5.0 V TTL / CMOS logic compatible inputs

• Over-current limiting (Regulation) via an internal constant-off-time PWM

• 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
