Middle Power Class-D Speaker Amplifiers Analog Input / BTL Output Class-D Speaker Amplifier BD5427MUV No.10075EBT07 ●Description BD5427MUV is a 7W + 7W stereo class-D power amplifier IC, developed for space-saving and low heat-generation applications such as low-profile TV sets. The IC employs state-of-the-art Bipolar, CMOS, and DMOS (BCD) process technology that eliminates turn-on resistance in the output power stage and internal loss due to line resistances up to an ultimate level. With this technology, the IC has achieved high efficiency of 80% (7W + 7W output with 8Ω load), which is the top class in the industry. The IC, in addition, employs a compact back-surface heat radiation type power package to achieve low power consumption and low heat generation and eliminates necessity of installing an external radiator, up to a total output of 14W. This product satisfies both needs for drastic downsizing, low-profile structures and powerful, high-quality playback of the sound system. ●Features 1) A high efficiency of 80% (7W + 7W output with 8Ω load), which is the highest grade in the industry and low heat-generation. 2) Driving a lowest rating load of 6Ω is allowed. 3) Pop noise upon turning power on/off and power interruption has been reduced. 4) High-quality audio muting is implemented by soft-switching technology. 5) High-reliability design provided with built-in protection circuits against high temperatures, against VCC shorting and GND shorting, against reduced-voltage, and against applying DC voltage to speaker. 6) A master/slave function allowing synchronization of multiple devices reduces beat noises. 7) Adjustment of internal PWM sampling clock frequencies (250kHz to 400kHz) allows easy protective measures against unwanted radio emission to AM radio band. 8) A compact back-surface heat radiation type power package is employed.

About absolute maximum ratings If an applied voltage or an operating temperature exceeds an absolute maximum rating, it may cause destruction of a device. A result of destruction, whether it is short mode or open mode, is not predictable. Therefore, provide a physical safety measure such as fuse, against a special mode that may violate conditions of absolute maximum ratings. 2. About power supply line As return of current regenerated by back EMF of output coil happens, take steps such as putting capacitor between power supply and GND as a electric pathway for the regenerated current. Be sure that there is no problem with each property such as emptied capacity at lower temperature regarding electrolytic capacitor to decide capacity value. If the connected power supply does not have sufficient current absorption capacity, regenerative current will cause the voltage on the power supply line to rise, which combined with the product and its peripheral circuitry may exceed the absolute maximum ratings. It is recommended to implement a physical safety measure such as the insertion of a voltage clamp diode between the power supply and GND pins. 3. Potential of GND (5, 18, 39, 42, and 43 pins) Potential of the GND terminal must be the lowest under any operating conditions. 4. About thermal design Perform thermal design with sufficient margins, in consideration of maximum power dissipation Pd under actual operating conditions. This product has an exposed frame on the back of the package, and it is assumed that the frame is used with measures to improve efficiency of heat dissipation. In addition to front surface of board, provide a heat dissipation pattern as widely as possible on the back also. A class-D power amplifier has heat dissipation efficiency far higher than that of conventional analog power amplifier and generates less heat. However, extra attention must be paid in thermal design so that a power dissipation Pdiss should not exceed the maximum power dissipation Pd. T jmax - Ta Tjmax: Maximum temperature junction = 150[℃] Pd 〔W〕 Maximum power dissipation Ta: Operating ambient temperature [℃] θja θja: Package thermal resistance [℃/W] 1 Po: Output power [W] diss O P P 1 〔W〕 Power dissipation η η: Efficiency 5. About operations in strong electric field Note that the device may malfunction in a strong electric field. 6. Thermal shutdown (TSD) circuit This product is provided with a built-in thermal shutdown circuit. When the thermal shutdown circuit operates, the output transistors are placed under open status. The thermal shutdown circuit is primarily intended to shut down the IC avoiding thermal runaway under abnormal conditions with a chip temperature exceeding Tjmax = 150℃, and is not intended to protect and secure an electrical appliance. Accordingly, do not use this circuit function to protect a customer's electrical appliance. 7. About shorting between pins and installation failure Be careful about direction and displacement of an LSI when installing it onto the board. Faulty installation may destroy the LSI when the device is energized. In addition, a foreign matter getting in between LSI pins, pins and power supply, and pins and GND may cause shorting and destruction of the LSI. 8. About power supply startup and shutdown When starting up a power supply, be sure to place the MUTEX pin (pin 28) at “L” level. When shutting down a power supply also, be sure to place the pin at “L” level. Those processes reduce pop noises generated upon turning on and off the power supply. In addition, all power supply pins must be started up and shut down at the same time. 9. About WARNING output pin (pin 26) and ERROR output pin (pin 27) A WARNING flag is output from the WARNING output pin upon operation of the high-temperature protection function and under-voltage protection function. And an ERROR flag is output from the ERROR output pin upon operation of VCC/GND shorting protection function and speaker DC voltage applying protection function. These flags are the function which the condition of this product is shown in. The use which aimed at the protection except for this product is prohibition. 10. About N.C. pins (pins 8, 9, 10, 11, 13, 24, 29, 30, 37, and 48) The N.C. (Non connection) pins are not connected with an internal circuit. Leave the pins open or connect them to GND. www.rohm.com © 2010 ROHM Co., Ltd.
