6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)
MIN NOM MAX UNIT
VM Power supply voltage 6.5 45 V
VI Logic input voltage (IN1, IN2) 0 5.5 V
fPWM Logic input PWM frequency (IN1, IN2) 0 200(2) kHz
Ipeak Peak output current(1) 0 3.6 A
TA Operating ambient temperature –40 125 °C
(1) Power dissipation and thermal limits must be observed
(2) The voltages applied to the inputs should have at least 800 ns of pulse width to ensure detection. Typical devices require at least 400 ns. If the PWM frequency is 200 kHz, the usable duty cycle range is 16% to 84%
