Motorola's new 2 mOhm high-side power switch can help designers of power electronics systems to better manage power distribution, reduce board space and increase system reliability. The MC33982 device is a mixed-signal, multichip IC designed to replace electromechanical relays, fuses and discrete devices in a variety of embedded systems.
This chip is suitable for systems that require up to 2 kW of power control. Examples are electrical actuators in appliances, power hand tools, dish positioning systems, and marine and automotive systems. Unlike mechanical relays, the silicon solution is not as susceptible to wear, contact malfunctions or corrosion. One major automobile manufacturer has already signed on to use the MC33982 IC in one of its primary platforms beginning in model year 2006, says Motorola.
The MC33982 device combines high-density, high-speed logic with precision analog and high-voltage, high-current power circuitry. It has built-in protection, logic level control and various configuration and communication features.
The MC33982 is housed in a 12 x 12 mm power quad flat pack no-lead package.
