TB9044AFNG Overview
Low-voltage operation (VB: 2.7V～), 3ch Power Supply for Sensors Safety mechanisms suitable for ASIL D systems
More and more safety-critical automotive systems, such as electric power steering (EPS) and braking, are required to satisfy ASIL D[Note1], the highest automotive safety integrity level prescribed in the ISO 26262 functional safety standards.
The new IC integrates various failure detection functions, such as high-voltage and low-voltage detection and overheat detection of power supply circuit, to monitor against the IC’s own failure, and a watchdog timer to monitor failure detection of the external microcomputer. An initial diagnosis circuit to detect latent faults in the failure detection circuits is also incorporated to secure higher functional safety.
