BTL driver - Mute function using the MUTE and BRAKE pin (Channel mute) Mute function for each channels can be obtained using the MUTE pin (pin19,pin21) and BRAKE pin (pin23). * When the voltage of the pin19 becomes low , the bias currents for CH3,CH4 are shut down and those corresponding channels are muted. On the contrary, when the voltage of the pin19 becomes high, the channel drivers operate normally. * When the voltage of the pin21,23 become high , the bias currents for CH1,CH2 are shut down and those corresponding channels are muted. On the contrary, when the voltage of the pin21,23 become low, the channel drivers operate normally.

GV 134 = 20 log | GV 2 = 20 log | 55 K | R + 11K 110 K | R + 7.5 K * R is an external resistor which is connected to input pins (pin17,18,20,22) - Power supply voltage IP9001 has two kinds of power supply pins. One is power supply for output stage(pin36), the others are signal power supply for pre driver(pin12, pin15). All power supply pins should be attached by-pass capacitor with each other. 2.

If the voltage of the CSPRT rises above 1.2V, then the DC/DC converter circuit is disabled. Disable time is dependent on the external capacitor “CSPRT” , Threshold voltage “VTH”, and internal constant current source “ISPRT”. t = CSPRT × VTH (sec ) IS P R T * VTH=1.2V, ISPRT=10uA - Soft start circuit IP9001 accomplishes soft-start-function by attaching external capacitor between DEAD pin and GND. Maximum duty can be changed by adding external resistor to DEAD pin (pin 4). t = CDEAD × ( R int + Re xt )(sec) * Rint=65K ohm, Rext=external resistor - Power off function When the input voltage of OFF(pin40) is low, then IP9001 starts charging to “CSPRT” with constant current “IOFF”. If the voltage of the CSPRT rises above 1.2V, then the DC/DC converter circuit is disabled. Disable time is dependent on the external capacitor “CSPRT” , Threshold voltage “VTH”, and internal constant current source “IOFF”. t = CSPRT × VTH (sec ) IO F F * VTH=1.2V, IOFF=20uA - Over voltage protection When the sensing voltage of SENS(pin1) is above 8.4V, then IP9001 starts charging to “CSPRT” with constant current “IHV”. If the voltage of the CSPRT rises above 1.2V, then the DC/DC converter circuit is disabled.
