| Parameter | Symbol | Typical NEC Value | Meaning | | :--- | :--- | :--- | :--- | | Supply Voltage | VCC | e.g., 7V | Max voltage before damage | | Power Dissipation | PD | e.g., 500mW | Use heatsink if exceeded | | Junction Temp | Tj | 150°C | Max internal temp |

Usually TO-220 or TO-263 (D2PAK) for heat dissipation Logic Level: Designed for low gate-drive voltages Key Technical Specifications nec b58944 datasheet

Because the NEC B58944 is supplied as an unprogrammed, hardware-level drive component, it does not hold a separate vehicle software image. Replacing a damaged chip does require you to re-flash or clone the vehicle’s specific immobilizer or tuning maps. You simply need to perform a precise hardware transplant. | Parameter | Symbol | Typical NEC Value
