Overview
The TDF8599ATH/N2/S6CY is a dual Bridge-Tied Load (BTL) Class-D car audio amplifier from NXP Semiconductors. It features an NDMOST-NDMOST output stage based on SOI BCDMOS technology, enabling high efficiency and low power dissipation for use with smaller heat sinks compared to standard Class-AB amplifiers. The device supports I2C-bus or non-I2C-bus operation modes, offering up to 15 selectable I2C addresses. Key electrical parameters include an operating voltage range of 8 V to 35 V, stereo mode output power of 135 W at 4 Ω (VP=35 V), and single channel output power of 250 W at 2 Ω (VP=35 V).
Feature Summary
- Dual BTL channels capable of driving 4 Ω loads in stereo mode or 2 Ω loads in parallel mode.
- Integrated load diagnostics including DC/AC load detection and fault condition reporting via I2C-bus.
- Advanced protection mechanisms including thermal foldback, overtemperature shutdown, short circuit protection, and load dump protection.
- Flexible clocking options with spread spectrum mode, frequency hopping, and phase staggering capabilities.
Applications
- Car audio systems
Procurement Notes
Verify the specific ordering suffix S6CY against official NXP documentation to confirm package type and reel specifications. Confirm current production status as automotive components may undergo lifecycle changes. Ensure compatibility with existing PCB footprints for the HSOP36 package before procurement.
Selection Notes
Select this component for applications requiring high-efficiency Class-D amplification with integrated diagnostic feedback. Consider the I2C-bus interface for complex system control and monitoring. Evaluate thermal management requirements based on the specified output power and ambient temperature conditions.
Part Context
This part belongs to the TDF8599A series of I2C-bus controlled dual channel Class-D power amplifiers. It is designed specifically for automotive environments, meeting AEC-Q100 qualification standards. The series offers scalable power solutions for various speaker configurations in vehicle infotainment systems.
Replacement Considerations
Check for direct substitutes within the TDF8599 family such as TDF8599CTH/N1 variants. Verify pinout compatibility and electrical parameter equivalence before substitution.
FAQ
How is the I2C-bus address selected?
Up to 15 I2C-bus addresses can be selected by adjusting the value of the external resistor connected between pins ADS and MOD.
What happens if the junction temperature exceeds 160 °C?
OverTemperature Protection (OTP) is tripped, causing the power stage to shut down immediately.
