TDA 16888

Comparator C8

The control of the pulse width modulation of the PWM section is taken over by

comparator C8 as soon as the soft start is finished. This is achieved by comparison of

the PWM output voltage at pin 14 (PWM IN) and the PWM voltage ramp at pin 15

(PWM RMP).

Comparator C9

By means of this extremely fast comparator sensing at pin 11 (PWM CS) peak current

limitation is realized. When being activated (VPWM CS > 1 V) it will immediately shut down

the gate drive of the PWM section (PWM OUT).

Comparator C10

By means of the threshold of 0.4 V the comparator C10 allows the PWM duty cycle to be

continuously controlled from 0 to 50%. As long as the ramp voltage at pin 15

(PWM RMP) is below this threshold the gate drive of the PWM section (pin 10,

PWM OUT) is turned off.
