Operation notes
(1) Power save
The power save input is an I / O circuit like the own shown in Fig.1.
The thermal derating characteristics of the power save pin is –8mV /
°
C, and the resistance will fluctuate
between
±
30% so be careful of the input voltage range.
(2) Hall input
The input circuit shown in Fig.4 is used for the Hall inputs.
The Hall elements can be connected either in series or in parallel.
(3) Thermal shutdown (TSD)
When the junction temperature reaches 175
°
C, the A1, A2, and A3 coil outputs go open circuit. The thermal
shutdown has approximately 15
°
C of hysteresis.
