Table 1: Electrical specifications
1 Typical values are defined at TA = +25°C and VDD = 12V, unless otherwise specified
2 Guaranteed by design and verified by characterization, not production tested
3 RPU and VPU are respectively the external pull-up resistor and pull-up power supply
4 If the Output is in Current Limitation longer than tCLON the Output is switched off in high-impedance state. The Output returns back in active state at next reaching of BOP or after
tCLOFF time interval
5 The Delay Time is the time from magnetic threshold reached to the start of the output switching
6 Output jitter is the unpredictable deviation of the Delay time
7 Maximum switching frequency corresponds to the maximum frequency of the applied magnetic field which is detected without loss of pulses
8 The Power-On Time represents the time from reaching VDD = VPOR to the first refresh of the output (first valid output state)
9 Power-On Slew Rate is not critical for the proper device start-up
