Note1. Momentary peak voltage (near the power Tr. block)
(1) Please design the voltage of PWM output terminal(OUT1, OUT2) as below.
overshoot : maximum 28V
undershot : maximum 4.5V
The very big ringing voltage would occur if the accidents such as short circuit of loud speaker happen.
Ringing voltage may destroy the Power Tr. Please caution against above voltage.
Please refer to Thermal De-rating shown on Page 6 about Heat decrease rate.
Please examine the restriction of an actual Pd value at the maximum temperature of assumption
because Ta=75
℃
max is the upper bound regulations of IC.
