Note 1:
Absolute Maximum Ratings indicate the limits beyond which damage may occur.
Note 2:
ESD Ratings is with Human Body Model: 100pF discharged through a 1500
resistor.
Note 3:
Operating ratings indicate conditions for which the device is intended to be functional, but may not meet the guaranteed specific performance limits. For guar-
anteed specifications and conditions, see the Electrical Characteristics.
Note 4:
Tested per VR Sensor Interface test circuit. See figures 8 and 9.
Note 5:
Minimum Detect Current is not production tested at +85C. Specifications is guaranteed through device characterization and Test Limits at 25C and 125C.
Note 6:
VR Sensor Interface Tdelay, measured from VR input sine wave zero-crossing to VR_OUT going high. See figure 9.
Note 7:
Electronic Timing Interface Tsetup, minimum time between Vcc
>
4.75V and RESET = 1.
Note 8:
Electronic Timing Interface Tsetup, minimum time between RESET = 1 and D0 = 1.
Note 9:
Electronic Timing Interface Tsetup, minimum time between D0 / D1 = valid and ENB = 1.
