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 be-
tween ±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 175C, the A
1,
A
2, and A3 coil outputs go open circuit. The thermal shut-
down has approximately 15C of hysteresis.
