Nec B58944 Datasheet |top| -

Common in EDC7 and EDC16 units for heavy vehicles like Iveco.

: The vehicle cuts out when the engine bay reaches full operating temperature, pointing to internal IC thermal fracturing.

The confirmed specification details for the NEC B58944 are limited. The following key parameters are derived from the most likely candidate for the underlying core component, the static RAM, which shares the same physical package and pin count.

The correct replacement is the SRAM, often sold with its Bosch markings D43256BGU-70Y . Reliable sources include:

The NEC B58944 is a dual operational amplifier IC designed for high-gain, high-speed applications. It features a high slew rate, low noise, and a wide bandwidth, making it suitable for use in a variety of analog circuits. The IC is housed in a standard 8-pin DIP package and operates on a single power supply voltage.

Based on the datasheet for the μPD43256BGU-70L equivalent, the B58944 typically features the following characteristics: Common in EDC7 and EDC16 units for heavy vehicles like Iveco

If you are performing a repair on an ECU, keep these factors in mind:

: The OBD-II scanner cannot establish a connection with the ECU.

However, this guide will help you in two ways: The following key parameters are derived from the

Operating the component beyond these thresholds can cause permanent silicon degradation or immediate failure. : -0.5V to +7.0V Input/Output Voltage ( VINcap V sub cap I cap N end-sub VOUTcap V sub cap O cap U cap T end-sub ) : -0.5V to Operating Temperature ( TAcap T sub cap A

Q: What are the typical applications of the NEC B58944? A: The NEC B58944 is commonly used in power supplies, motor control, and lighting systems.
