All rights reserved. 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 – 3.0A). 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 3.0A of transient current. On a continuous basis, each output can simultaneously (with all outputs "ON") handle 0.5A 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. Features • Designed to operate over wide supply voltages of 5.5 to 26.5V • Interfaces to microprocessor using 8-bit SPI I/O protocol up to 3.0MHz • 1.0A peak current outputs with maximum RDS(ON) of 1.8Ω at TJ - 150°C • Outputs current limited to accommodate in-rush currents associated with switching incandescent loads • Output voltages clamped to 65V during inductive switching • Maximum sleep current (IPWR) of 25µA • Maximum of 4.0mA IDD during operation • Pb-free packaging designated by suffix code EG Figure 1. 33298 Simplified Application Diagram LOW SIDE SWITCH DW SUFFIX EG SUFFIX (PB-FREE) 98ASB42344B 24 SOICW 33298 ORDERING INFORMATION Device Temperature Range (TA) Package MC33298DW/R2 -40°C to 125°C 24 SOIC MCZ33298EG/R2 MCU 33298 VDD V PWR SFPD CS SCLK SI RESET SO VDD VPWR OP 0 OP 1 OP 2 OP 3 OP 4 OP 5 OP 6 OP 7 GND |
