33298 (0.4
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 moder-
ate 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
ing up to 3.0 A of transient current. On a contin-
uous 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, "cas-
cadable" fault reporting, independent internal
60 V clamping of outputs, output-specific diag-
nostics, and independent over temperature
shutdown of outputs.
