Table 2: electrical specifications
1
Typical values are defined at TA = +25ºC and VDD = 12V
2
Based on device characterization results, not subject to production test
3
Measured between 0.1*VPU and 0.9*VPU
4
RPU and VPU are respectively the external pull-up resistor and pull-up power supply
5
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
6
Controlled delay between direction (DIR) signal update and speed (SP) signal update
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 = 2.7V to the first refresh of the SP output
