PD=IOUT×VO(sat)+(IVCC-IOUT) ×VCC+VIA×IIA+VIB×IIB
IOUT is the output current through the motor;VO(sat) is the sum of output transistor high- and low-side
voltages; IVCC is the current through the pin VCC; VCC is the voltage of pin VCC；VIA and VIB are the input
voltage of pin IA and IB respectively;IIA and IIB are the input current of pin IA and IB respectively. PD is mostly
determined by IOUT×VO(sat).
Recommended operating conditions indicate limits beyound which damage to the device may
occur.Electrical specifications do not apply when operating the device outside of its stated operating
conditions.
