FUNCTIONAL DESCRIPTION

FUNCTIONAL PIN DESCRIPTION

SYSTEM ACTUATOR ELECTRICAL

CHARACTERISTICS (AT ROOM TEMPERATURE)

All drains should have a 0.01

μF filter capacitor connected

to ground. Any unused output pin should not be energized. A

20 Ω resistor to the battery is required to prevent false open

load reporting. There must also be a maximum of 100 Ω of

resistance from VPWR to ground, keeping battery-powered

loads OFF when the IC is powered down. However, all loads

should be powered by VPWR to protect the device from full

transient voltages on the battery voltage.

POWER-UP

The device is insensitive to power sequencing for VPWR

and VDD, as well as intolerant to latch-up on all I/O pins.

Upon power-up, an internal power-ON reset clears the serial

registers, allowing all outputs to power up in the off-state

when parallel control pins are also low. Although the serial

initialize the outputs with an SPI command prior to changing

the MODE pin from a high to a low state. This assures known

output states when MODE is low.
