Product details
Overview
TDA75610LVPDTR from STMicroelectronics is a quad-channel Class SB automotive audio power amplifier in PowerSO36 package, delivering up to 4 × 45 W into 4 Ω at 14.4 V with 10% THD, full I²C diagnostics (DC/AC load detection, clipping threshold selection), and operation down to 6 V for start-stop systems.
For engineers reviewing the TDA75610LVPDTR datasheet, TDA75610LVPDTR pinout, TDA75610LVPDTR application, or TDA75610LVPDTR equivalent, key selection considerations include its 4-channel bridge output architecture, I²C-configurable gain (26 dB / 16 dB), thermal warning thresholds (125–160 °C), 2 Ω driving capability (64 W max), and integrated fault diagnostics per channel.
Technical Context
The TDA75610LVPDTR implements ST's patented Class SB efficiency architecture-combining BCD process technology with MOSFET/DMOS output stages-to reduce quiescent current (165–250 mA) and average power dissipation versus Class AB while maintaining low THD (0.015% typ. at 1 W, 1 kHz). It integrates four independent short-circuit protections and linear thermal foldback with three programmable warning levels (125 °C, 145 °C, 160 °C).
I²C bus control enables real-time diagnostics including DC offset detection, AC load impedance classification, and configurable clipping detection (1–15% THD threshold). The device supports dual-gain modes via I²C or hardware pins, and features SVR suppression >60 dB (100 Hz–10 kHz) and ITU-R pop filtering for clean mute/play transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Power | 4 × 45 W max @ 14.4 V, 4 Ω, 10% THD - delivers full-range audio for premium car radio front/rear speaker sets without external heatsinking under typical supply conditions. |
| Supply Voltage Range | 6–18 V - supports engine start-stop battery profiles (down to 6 V) and withstands cranking transients up to 50 V peak (50 ms). |
| THD+N | 0.015% typ. @ 1 W, 1 kHz, STD mode - ensures high-fidelity reproduction with minimal harmonic distortion in critical mid-band listening range. |
| I²C Diagnostics | Per-channel DC/AC load detection, clipping threshold (1–15%), and thermal warnings - enables OEM-level speaker health monitoring and predictive fault reporting over single 2-wire bus. |
| Thermal Protection | Three-stage linear thermal warning (125/145/160 °C) + fast muting - provides progressive system response before junction exceeds 150 °C, preserving reliability during sustained high-power operation. |
| Gain Configuration | 26 dB (low-noise line-out) or 16 dB (high-sensitivity speaker drive) - selectable via I²C or hardware pin, optimizing SNR or headroom based on downstream signal chain. |
| Short-Circuit Protection | Four independent channel-level protections with <1.2 V GND-short detection - prevents latch-up and damage during speaker wire miswiring or connector faults. |
Pinout & Package
Package: PowerSO36 (slug-up, thermally enhanced exposed die pad), RoHS-compliant, designed for high-power automotive PCB mounting with direct heatsink interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB (Pin 1) | Exposed thermal pad | Primary thermal path to PCB copper pour or heatsink; must be soldered for Rth j-case ≤ 1 °C/W compliance. |
| OUT1+ to OUT4− (Pins 2,4,8,10,17,19,22,33,34,36) | Differential speaker outputs | Four fully independent bridge outputs supporting 2 Ω–4 Ω loads; each pair drives one speaker without external LC filters. |
| CK (Pin 3), DATA (Pin 7) | I²C clock/data bidirectional lines | Enable configuration of gain, mute timing, diagnostic thresholds, and real-time fault readback; support standard-mode (100 kHz) I²C protocol. |
| STBY (Pin 11) | Hardware standby/mute control | Three-state logic interface: <1.2 V = standby (90 dB attenuation), 2.9–3.5 V = mute (80 dB), >4.5 V = active - allows microcontroller or discrete switch control. |
| CD (Pin 16) | Clipping detector open-drain output | Asserts low when output THD exceeds user-selected threshold (1–15%); used for dynamic volume limiting or DSP feedback without I²C polling. |
| SVR (Pin 24) | Supply voltage rejection compensation | Connects to external RC network to improve ripple rejection during battery transients - critical for noise-free audio during engine cranking. |
Key Features
| Feature | Design Value |
|---|---|
| Class SB Efficiency Architecture | Reduces average power dissipation by ~40% vs. Class AB at same output level, enabling compact thermal design and lower system cooling requirements. |
| Per-Channel Diagnostic Reporting | I²C-accessible status registers report open-load, short-to-GND/VCC, clipping, thermal warning, and DC offset per channel - eliminates need for external sense circuitry. |
| Start-Stop Low-Voltage Operation | Stable 4 × 25 W output at 6 V supply enables seamless audio playback during engine stop, meeting latest OEM fuel-efficiency mandates. |
| Robust Misconnection Immunity | Withstands reverse battery, output short-to-ground/VCC, and floating inputs without latch-up or permanent damage - reduces field failure rates in mass production. |
| ITU-R Pop Suppression | Integrated analog pop filter limits transient voltage to ±7.5 mV during mute/play transitions - meets automotive EMC and listener comfort standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel automotive amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDA75610LVH | Same silicon, Flexiwatt27 horizontal package - larger footprint, higher Rth j-case (1.2 °C/W), no exposed thermal slug. | Used in legacy designs with through-hole assembly or limited PCB copper area; lacks PowerSO36's thermal performance. | Select only if mechanical compatibility with existing Flexiwatt27 layout is required and thermal margin ≥15 °C is available. |
| TDA75610LVSMTR | Same silicon, Flexiwatt27 SMD package - smaller than PowerSO36 but still requires external heatsink; Rth j-case = 1.1 °C/W. | Preferred for reflow-assembled boards where PowerSO36 tooling is unavailable, but thermal performance is 10% lower than LVPDTR. | Choose when SMT process constraints prohibit PowerSO36, and average output power remains ≤35 W/channel. |
Compared with TDA75610LVH and TDA75610LVSMTR, the TDA75610LVPDTR offers superior thermal resistance (≤1.0 °C/W), smaller footprint, and optimized thermal pad soldering for high-reliability automotive environments - making it the preferred choice for new designs targeting maximum power density and start-stop robustness.

FAQ
What is the minimum supply voltage for full 4 × 45 W output?
The TDA75610LVPDTR delivers its rated 4 × 45 W maximum output only at VS ≥ 14.4 V with 4 Ω loads and 10% THD. At 6 V (start-stop condition), maximum output drops to 5 W per channel into 4 Ω. Full power requires ≥13.5 V supply with proper decoupling and thermal management.
How does the I²C diagnostic system detect speaker open-circuits?
The device performs DC offset measurement on each output pair during startup and continuously monitors AC load impedance via current sensing. An open circuit is flagged when DC offset exceeds ±80 mV and AC current falls below threshold - reported via dedicated I²C register bits for each channel.
Can the clipping detector pin (CD) be used without I²C communication?
Yes. The CD pin operates independently as an open-drain output: it pulls low when output THD exceeds the hardware-selected threshold (set by IB1 pin state). No I²C interaction is needed for basic clipping indication, enabling simple LED alerts or DSP interrupt triggering.
Is the PowerSO36 package lead-free and RoHS-compliant?
Yes. The TDA75610LVPDTR uses a RoHS-compliant, lead-free PowerSO36 package with matte tin plating. Its thermal pad is designed for standard Pb-free reflow profiles (peak 260 °C), and the device meets JEDEC J-STD-020 moisture sensitivity level MSL3.
