HA13173AH

Multiple Voltage Regulator for Car Audio

REJ03F0227-0100

Rev.1.00

Jan 16, 2007

Description

The HA13173AH is a multiple voltage regulator for car audio system. This IC has 5.0 V output for a microcontroller,

3.3 V output for a Digital Signal Processor, 8.0 V output for CD driver, 8.4 V output for audio control, 8.4 V output for
illuminations, and high side switch output for external output.

The HA13173AH also has FREG that is possible to control external PNP transistor. It is adjustable output voltage by
changing an external resistor.

Functions

• Standby current is 100 µA max.

• The Vdd output for microcontroller has backup function, by independent power supply line.

• Low saturation output (PNP output) used for audio output.

• Output current limit circuit to avoid device destruction caused by shorted output, etc.

• High surge input protector against VB and VBUP.

• Built in a thermal shutdown circuit to prevent against the thermal destruction.

• The package is PRSS0015DA-C (SP-15TGV).

destruction or for the purpose of any other military use. When exporting the products or technology described herein, you should follow the applicable export control laws
and regulations, and procedures required by such laws and regulations.

4. All information included in this document such as product data, diagrams, charts, programs, algorithms, and application circuit examples, is current as of the date this
document is issued. Such information, however, is subject to change without any prior notice. Before purchasing or using any Renesas products listed in this document,
please confirm the latest product information with a Renesas sales office. Also, please pay regular and careful attention to additional and different information to be
disclosed by Renesas such as that disclosed through our website. (http://www.renesas.com )

5. Renesas has used reasonable care in compiling the information included in this document, but Renesas assumes no liability whatsoever for any damages incurred as a
result of errors or omissions in the information included in this document.

6. When using or otherwise relying on the information in this document, you should evaluate the information in light of the total system before deciding about the applicability
of such information to the intended application. Renesas makes no representations, warranties or guaranties regarding the suitability of its products for any particular
application and specifically disclaims any liability arising out of the application and use of the information in this document or Renesas products.

7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas products are not designed, manufactured or tested for applications
or otherwise in systems the failure or malfunction of which may cause a direct threat to human life or create a risk of human injury or which require especially high quality
and reliability such as safety systems, or equipment or systems for transportation and traffic, healthcare, combustion control, aerospace and aeronautics, nuclear power, or
undersea communication transmission. If you are considering the use of our products for such purposes, please contact a Renesas sales office beforehand. Renesas shall
have no liability for damages arising out of the uses set forth above.

8. Notwithstanding the preceding paragraph, you should not use Renesas products for the purposes listed below:
(1) artificial life support devices or systems
(2) surgical implantations
(3) healthcare intervention (e.g., excision, administration of medication, etc.)
(4) any other purposes that pose a direct threat to human life
Renesas shall have no liability for damages arising out of the uses set forth in the above and purchasers who elect to use Renesas products in any of the foregoing
applications shall indemnify and hold harmless Renesas Technology Corp., its affiliated companies and their officers, directors, and employees against any and all
damages arising out of such applications.

9. You should use the products described herein within the range specified by Renesas, especially with respect to the maximum rating, operating supply voltage range,
movement power voltage range, heat radiation characteristics, installation and other product characteristics. Renesas shall have no liability for malfunctions or damages
arising out of the use of Renesas products beyond such specified ranges.

10. Although Renesas endeavors to improve the quality and reliability of its products, IC products have specific characteristics such as the occurrence of failure at a certain
rate and malfunctions under certain use conditions. Please be sure to implement safety measures to guard against the possibility of physical injury, and injury or damage
caused by fire in the event of the failure of a Renesas product, such as safety design for hardware and software including but not limited to redundancy, fire control and
malfunction prevention, appropriate treatment for aging degradation or any other applicable measures. Among others, since the evaluation of microcomputer software
alone is very difficult, please evaluate the safety of the final products or system manufactured by you.

11. In case Renesas products listed in this document are detached from the products to which the Renesas products are attached or affixed, the risk of accident such as
swallowing by infants and small children is very high. You should implement safety measures so that Renesas products may not be easily detached from your products.
Renesas shall have no liability for damages arising out of such detachment.

12. This document may not be reproduced or duplicated, in any form, in whole or in part, without prior written approval from Renesas.
