The 33926 is a SMARTMOS 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 m maximum R DS(on) at 150 °C (each H-Bridge MOSFET)
• 3.0 V and 5.0 V TTL / CMOS logic compatible inputs
• Overcurrent 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)
APPLICATIONs
• Electronic Throttle Control (ETC)
• Exhaust Gas Recirculation (EGR)
• Turbo Flap Control
• Industrial and Medical pumps and motor control
