STATIC ELECTRICAL CHARACTERISTICS

Table 4. Static Electrical Characteristics

Characteristics noted under conditions 4.5 V ≤ VDD ≤ 5.5 V, 9.0 V ≤ VPWR ≤ 16 V, -40°C ≤ TA ≤ 125°C, unless otherwise noted.

Typical values noted reflect the approximate value with VBAT = 13 V, TA = 25°C.

Notes

16.

SPI inputs and outputs operational. Fault status reporting may not be fully operational within this voltage range. Outputs remain

operational somewhat below this VPWR range, but RDS(ON) will increase, causing power dissipation to increase. Outputs will re-

establish their instructed state following a VPWR interruption as long as VDD remains non-interrupted.

17.

This parameter is guaranteed by design, but it is not production tested.

18.

Measured with the RST pin held at a logic high state. Outputs can be OFF or ON or in any combination thereof.

19.

Device incorporates a power-ON reset function. For VDD less than the Undervoltage Lockout Threshold voltage, all data registers are

reset and all outputs are disabled.

20.

Output Fault Detect Threshold with outputs programmed OFF. Output fault detect thresholds are the same for output opens and shorts.
