Nec B58944 Datasheet

Frequently paired with an NPN counterpart for push-pull configurations.

Q: What is the maximum drain-source voltage of the NEC B58944? A: The maximum drain-source voltage (VDS) of the NEC B58944 is 100V.

: Active HIGH. Used for power-down sequencing and battery backup routing. 28 nec b58944 datasheet

While a standalone "B58944" datasheet is rare because it's an OEM part number, you should search for the μPD43256B datasheet from NEC/Renesas to get full electrical timing and pinout details.

: Active LOW. Gates data from the I/O pins into the selected memory cell. 26 Frequently paired with an NPN counterpart for push-pull

Typically rated at 70ns (indicated by the "-70" suffix). Manufacturer: NEC Electronics (now Renesas). Automotive Applications

70 ns (indicated by the "-70L" suffix in its equivalent part number). Supply Voltage: Typically 5V (standard for the $\mu$PD43256 series). Current Consumption: : Active HIGH

: Provides specific chips for Bosch engine drive repairs. B58944 - datasheet, pdf, info, parameters, stock - Elparts

: Sustained thermal cycling in engine-bay environments can fracture the solder joints on the SOP-28 package, leading to intermittent signal loss.

: It is integrated into several generations of Bosch hardware, including the ME7.4.4, ME7.5, ME7.5.10, ME7.9.6, ME7.9.20, EDC7, and EDC16 ECU platforms. These modules manage engine mapping across common consumer vehicle brands like Volkswagen, Audi, Honda, and Iveco.

The NEC B58944 operates in high-vibration, high-temperature engine environments, making it one of the more frequently damaged parts on an Auto ECU circuit board. Root Causes of Failure
