FOperation notes

(1) Start / stop pin

The I / O equivalent circuit of the start / stop pin is shown

in Fig. 4. The pin has a temperature dependence of

–7mV / C, and its resistance can vary ± 30%. The voltage

on this pin should be less than Vreg.

(3) Torque limit pin

The output current can be limited by applying a voltage

to the torque limit pin. Control is provided so that this pin

will have the same potential as the power ground pin

(RNF). Note that there is a voltage offset on this pin. The

RNF-pin voltage is 0.325V when the TL-pin voltage is 0.4V

(typical) and the RNF-pin resistance is 0.5Ω. Note that the

voltage offset changes with the RNF-pin resistance. Con-

nect the TL Vreg (pin 23) when the TL pin is not used.

(2) Hall input

The I / O equivalent circuit of the Hall input pins is shown

in Fig. 5. The Hall devices can be connected in either se-

ries or parallel. The input Hall signal should be within the

range of the Hall input common-mode voltage.

(4) Thermal shutdown circuit

The thermal shutdown circuit puts the driver outputs (A1,

A2, and A3) to the open state at the temperature of 175_C

(typical). The circuit is deactivated when the temperature

drops to about 150_C.
