5 / 12 page 1998 Sep 23 5 Philips Semiconductors Product specification 2 × 25 W BTL stereo car radio power amplifier with differential inputs and diagnostic outputs TDA8566Q Short-circuit diagnostic (pin 15) When a short-circuit occurs at one or more outputs to ground or to the supply voltage, the output stages are switched off until the short-circuit is removed and the device is switched on again (with a delay of approximately 20 ms after the removal of the short-circuit). During this short-circuit condition, pin 15 is continuously low. When a short-circuit occurs across the load of one or both channels, the output stages are switched off for approximately 20 ms. After approximately 50 µs the load condition is again checked to see if the short-circuit is still present. Due to this duty cycle of 50 µs/20 ms the average current consumption during this short-circuit condition is very low (approximately 40 mA). During this short-circuit condition, pin 15 is low for 20 ms and high for 50 µs (see Fig.4). The power dissipation in any short-circuit condition is very low. Temperature pre-warning (pin 15) When the junction temperature (Tvj) reaches 145 °C, pin 15 will become continuously low. Open-collector outputs Pins 4 and 15 are open-collector outputs, therefore more devices can be tied together. Pins 4 and 15 can also be tied together. An external pull-up resistor is required. Differential inputs The input stage is a high-impedance fully differential balanced input stage that is also capable of operating in a single-ended mode with one of the inputs capacitively coupled to an audio ground. It should be noted that if a source resistance is added (input voltage dividers) the CMRR degrades to lower values.
