Setting the Frequency of Low Frequency PWM
Generator: An internal trimmed low frequency
oscillator generates a ± 3% accurate frequency on
CTPWM pin with external capacitors. The capacitor
values versus operation frequencies are as bellow:
[ ]FLFPWM
=
4512
.............(3)
CCTPWM + 0.005 nF
Note: Above equation (3) is valid only when operating
frequency is between 150Hz ~ 1.5KHz
The logic high output of pin PWMOUT is made by an 2.5V
DC voltage and the floating state makes the logic low
portion. MODSEL pin provides the polarity selection of
LF_PWM generator. If MODSEL pin is 0V, a 0% duty cycle
is obtained when PWMDC < 1.0V. If this pin is pulled to
IC VDD level, 0% duty cycle is obtained while PWMDC>
2.5V.
Note: BIT3193 limits the maximum duty cycle to ~ 92 %.
PWMOUT sends the pulses when ISEN >1.3V or TIMER
>2.5V.
UVLO: The under-voltage-lookout circuit turns the output
driver off when supply voltage drops too low. Whole
system includes the protection and timing circuits are reset
(pin TIMER =0) in low VDD state.
