MCZ33298

www.DataSheet4U.com Freescale Semiconductor Technical Data Document Number: MC33298 Rev. 5.0, 10/2006 Eight Output Switch with Serial Peripheral Interface I/O The 33298 is a smart eight-output low-side power switch. It is a versatile device incorporating an 8-bit serial-in shift register to control an 8-bit parallel output latch providing control of eight independent "ON/OFF" output switches. Applications include the control of solenoids, relays, lamps, small DC-motors, and other moderate current loads (1.0 – 3.0 A). The 33298 interfaces directly with a microcontroller to control various inductive or incandescent loads. Input control is fast. Data rates are guaranteed to 2.0 MHz but the device is capable of rates to 8.5 MHz @ 25°C. Each output uses high-efficiency MOSFET power transistors configured with open drains. Each low "ON" resistance output (0.4 Ω RDS(ON) @ 25°C) is capable of sinking up to 3.0 A of transient current. On a continuous basis, each output can simultaneously (with all outputs "ON") handle 0.5 A of current when the device is soldered onto a typical PC board. Higher output currents are dependent on the number of outputs simultaneously "ON". The circuit's innovative monitoring and protection features include very low standby current.
