E

E - Unresolved Single-Letter MPN | Component Inquiry

The XAIPART internal database identifies MPN E as a single-letter manufacturer part number placeholder rather than a resolvable electronic component. The supplied manufacturer, distributor, and cross-reference results contain only general component-search pages; none identifies a device, manufacturer, electrical class, package, pinout, order code, or technical datasheet for E. Consequently, no verified voltage rating, current rating, frequency, memory size, package dimensions, operating temperature, lifecycle class, environmental qualification, or unit price can be assigned. A manufacturer part number normally provides a structured identifier that distinguishes a catalog item among ICs, discrete semiconductors, passives, connectors, sensors, and other products. The isolated character E does not provide enough information to perform that identification. What is an MPN? A manufacturer part number is a vendor-assigned key used for purchasing, technical documentation, lifecycle management, quality traceability, and electronic component cross-referencing. For some product families, a complete MPN encodes the device function, performance grade, package, temperature range, qualification tier, and reel or tube ordering information. Because those fields are absent for E, treating it as a particular component would require unsupported inference. The verified search results do not establish whether E belongs to a passive component, discrete semiconductor, integrated circuit, connector, sensor, or other product class. They therefore cannot establish a valid category, pin-compatible substitute, or drop-in alternative. The cross-reference evidence consists of general tools that expressly require a complete manufacturer part number before presenting parametrically similar options. No candidate can be checked for package dimensions, pin assignments, electrical limits, thermal behavior, or manufacturer function. Practical component selection requires an unambiguous ordering identity. An engineer should provide the full manufacturer part number, manufacturer name, top-marking or package marking, schematic reference, BOM line context, or an image of the physical part. A marking can be ambiguous because several manufacturers may use similar short codes, so it should be used together with the manufacturer, package, and electrical role. Once the identity is resolved, the datasheet can establish ratings, pinout, ordering information, lifecycle status, and recommended alternatives. This inquiry page intentionally preserves E as an unresolved placeholder and does not fabricate specifications, pricing, pin assignments, compliance claims, or substitute parts. The internal database entry and general distributor search pages support that conclusion. This page separates verified identity evidence from unsupported assumptions, helping procurement and engineering teams avoid ordering errors, counterfeit risk, PCB incompatibility, and invalid cross-reference decisions.

E-L9637D013TR

E-L9637D013TR - ISO 9141 K-Line Bus Driver/Transceiver | STMicroelectronics

The STMicroelectronics E-L9637D013TR is a monolithic ISO 9141 K-Line bus driver and transceiver designed for automotive on-board diagnostics (OBD-II) and bidirectional serial communication, packaged in an 8-pin SOIC (SO-8, 0.154 inch/3.90 mm width) and shipped in Tape & Reel (TR). It operates from a wide 4.5 V to 36 V supply, tolerates 40 V transients, and survives reverse-battery connection down to VS = -24 V while drawing approximately 2.3 mA supply current. What is a K-Line / ISO 9141 transceiver? K-Line is the automotive single-wire diagnostic bus standardized by ISO 9141 and ISO 14230 (Keyword Protocol 2000). It typically operates at ~10.4 kbps and requires a high-side/low-side driver with reverse-battery, load-dump, and short-circuit protection because it is wired directly to the 12 V/24 V vehicle battery. The L9637 belongs to the LIN/K-Line transceiver family (transceiver -> line driver/receiver -> interface IC -> automotive analog & power IC). Key features include K output current limitation of typ. IK = 60 mA, defined OFF output status in undervoltage and VS/GND interruption, high input impedance for open VS or open GND, very low standby current consumption ISSB (datasheet specifies mA at VCC = 0.5 V), and integrated reverse-battery/overvoltage safeguards. The 1A.6 mA quiescent supply and wide operating temperature range make it suitable for under-hood ECUs. Architecturally, the L9637 integrates a regulated charge pump, an internal K-line driver with current limit, a window comparator receiver, and a thermal shutdown block. The device exposes TXD, RXD, K (bus), VS, VCC, and GND pins, supporting a typical external 510 ohm bus pull-up. Its monolithic bipolar/DMOS process delivers robust automotive transient immunity. Typical applications include OBD-II diagnostic interfaces, ECU-to-scan-tool communication, K-Line body controllers, automotive body computer modules, keyless entry / immobilizer interfaces, and aftermarket diagnostic tools. Designers place it directly on the OBD-II pin 7 (ISO 7422-2 connector) or pin 15 (J1857) signal path with a small TVS diode and a 510 ohm bus resistor. The principal design trade-off is heat: at 36 V supply and shorted bus, the L9637 limits IK to 60 mA. Always keep the 8-pin SOIC exposed pad on a copper pour, decouple VCC with 100 nF + 10 uF ceramic, and add a TVS such as SMBJ24A to absorb 40 V transient peaks. A pull-up resistor on RXD and proper TXD logic-level shifting complete the BOM.

In the hierarchy of audio electronics, a BTL amplifier is a type of linear amplifier that uses a bridge configuration to double the voltage swing across the load, effectively quadrupling the output power compared to a single-ended amplifier with the same supply voltage. This makes BTL amplifiers ideal for automotive applications where the battery voltage is limited to 12V or 14.4V, and high output power is required without using bulky transformers or switching converters. Key features of the E-TDA7391PDTR include a wide operating supply voltage range of 8V to 18V, a low quiescent current of 120mA, and a high output power of 40W per channel at 10% THD. The device also features standby and mute functions for power management, a pop-free turn-on/off sequence, and full short-circuit and thermal protection. The PowerSO-20 package has an exposed pad that enhances heat dissipation, allowing continuous operation at high power levels without external heatsinks in many applications. The E-TDA7391PDTR uses a complementary NPN/PNP output stage with a class-AB biasing scheme, which provides low crossover distortion and high linearity. The device incorporates a sophisticated protection circuitry that includes output short-circuit protection, over-temperature shutdown, and load dump protection, ensuring reliable operation in harsh automotive environments. The standby and mute pins allow for easy system-level power management, reducing power consumption when the audio system is not in use. Typical applications include car radio head units, multimedia systems, and aftermarket audio amplifiers. The high output power and low distortion make it suitable for driving mid-range and subwoofer speakers in automotive sound systems. The device can also be used in home theater systems and portable PA systems where a compact, high-power amplifier is required. When designing with the E-TDA7391PDTR, it is essential to provide adequate power supply decoupling with a 1000uF electrolytic capacitor and a 100nF ceramic capacitor close to the supply pins. The exposed pad must be soldered to a large copper area on the PCB to ensure proper thermal management. Additionally, the standby and mute pins should be controlled with a microcontroller or a simple RC network to ensure a pop-free power-up sequence.

Built on the Gecko low-energy platform, the EFM32G200F64-QFN32 targets energy-sensitive embedded applications where short wake-up time and multiple low-power modes are mandatory, providing 24 digital I/O pins, two 16-bit timers, and a flexible energy management system that delivers Cortex-M3 throughput at substantially lower active and sleep current than legacy 8/16-bit parts. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and a wide range of peripherals such as timers, ADC/DAC, communication interfaces, and GPIO. The Cortex-M3 family specifically is a Harvard-architecture 32-bit RISC core with Thumb-2 instruction set, deterministic interrupt handling, and an optional Memory Protection Unit. The EFM32 Gecko series places that core inside a power-aware system hierarchy (MCU -> Cortex-M3 MCU -> low-energy MCU -> ARM Cortex family -> 32-bit embedded processor), giving it a clear positioning between general-purpose Cortex-M3 parts and ultra-low-power Cortex-M0+ devices. Key differentiating features of the EFM32G200F64-QFN32 include the integrated Wake-up Interrupt Controller (WIC) that allows peripherals to wake the CPU directly from deep-sleep without an enabled system clock, and the LESENSE / peripheral reflex system that lets sensor interfaces run autonomously.
