BAR88-02V E6327

The BAR88-02V E6327 detects, internally, whether or not an abnormal amplifier output offset   has occurred, and outputs this signal from pin 25. Applications can prevent speaker burnout and other problems by   having the system microcontroller detect this pin 25 output signal and control either the standby state or the power   supply. (An abnormal output offset may be caused by, for example, input capacitor leakage current.)The pin 25 signal is turned off by setting pin 1 to the ground potential.Available either in sensitive (TS8) or standard (TN8 / TYN) gate triggering levels, the 8A SCR series is suitable to fit all modes of control, found in applications such as overvoltage crowbar protection, motor control circuits in power tools and kitchen aids, inrush current limiting circuits, capacitive discharge ignition and voltage regulation circuits... Available in through-hole or surface-mount packages, they provide an optimized performance in a limited space area. Output Capacitors (Optional) For applications with load transients (sudden changes in load current), regulator response will benefit from an external output capacitance. The recommended output capacitance of 100 µF will allow the module to meet its transient response specification (see product data sheet). For most applications, a high quality computer-grade aluminum electrolytic capacitor is adequate.

These capacitors provide decoupling over the frequency range, 2 kHz to 150 kHz, and are suitable when ambient temperatures above 0 C. For operation below 0 C tantalum, ceramic or Os-Con type capacitors are recommended. When using one or more non-ceramic capacitors, the calculated equivalent ESR should be no lower than 4 m (7 m using the manufacturers maximum ESR for a single capacitor). A list of preferred low-ESR type capacitors are identified in Table 1-1.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
