Richtek’s RTQ2588-QB is a high-precision, low-power voltage detector rest IC specifically designed for automotive systems. It is AEC-Q100 qualified and supports ASIL-B functional safety compliance, addressing the stringent reliability and safety demands of automotive electronics.
With an ultra-low quiescent current—typically 3.5μA and a maximum of 7μA—RTQ2588-QB ensures stable operation even under high-temperature conditions, making it particularly well-suited for low-power platforms requiring long standby durations. It delivers ±0.78% voltage detection accuracy across the full temperature range, enabling precise over-voltage and under-voltage monitoring for timely system protection. The integrated self-diagnostic circuitry enhances fault detection capability and reinforces the overall functional safety system.
By combining accuracy, power efficiency, and safety in a single compact solution, RTQ2588-QB simplifies system design while optimizing performance. It has already been evaluated and adopted by Tier-1 automotive manufacturers and is ideal for power monitoring in systems that demand high stability and energy efficiency.
