System Actuator Electrical Characteristics (at Room

Temperature)

All drains should have a 0.01 µF filter capacitor connected to

ground. Any unused output terminal 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 terminals. 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 terminals are also low. Although the serial

register is cleared by this power-ON reset, software must still

initialize the outputs with an SPI command prior to changing the

MODE terminal from a high to a low state. This assures known

output states when MODE is low.
