|Highly Functional Low-noise LDO Regulator|
|Millimeter wave radar/sensing camera unit for ADAS and autonomous driving systems|
System construction with a functionality safety guarantee is required for millimeter wave radar/sensing camera units used for automotive ADAS and autonomous driving systems. Asahi Kasei Microdevices Corporation, (AKM), has launched low-noise LDO regulators, the AP1161AB and the AP1163ABN, which meet functional safety *1. These products incorporate a high-precision monitoring function to the output voltage and a self-diagnostic function, achieving functional safety.
*1: ISO26262 requirements for functional safety requirements can easily be achieved when utilized these devices.
The AP1161ABN/AP1163ABN monitors the output voltage to detect undervoltage and overvoltage status. If the status is met, a flag signal is sent to the MCU.
Failure of the monitoring function can be detected by inputting, "H", signal to the DIAG pin. By incorporating this function into the system, periodic fault detection during operation is available.
The AP1161ABC/1163ABC achieves output noise of 180 nV/√Hz, (at 10kHz), and PSRR of 78dB, (at 1kHz) *2. This exceeds the requirements of in-vehicle communications for severe noise and RF power supply requirements.
*2: PSRR of the AP1163ABN. The AP1161ABN has a PSRR of 76 dB, (at 1 kHz).
