Five-rail supervisor in a 16-SOIC
The Maxim Integrated MAX8213ACSE is a multi-voltage supervisor that monitors five independent supply rails, each with an adjustable threshold voltage. It asserts an active-low reset signal (open-drain or open-collector output) when any monitored voltage falls below its programmed threshold, and holds reset for a minimum of 1 ms after all rails return to tolerance. This part is intended for commercial-temperature (0°C to 70°C) equipment where multiple supply voltages need sequenced or supervised startup and fault detection.
What the five adjustable thresholds mean for your BOM
Five adjustable threshold voltages let you set each trip point independently via external resistor dividers. That flexibility is useful when the system uses non-standard rail voltages or when you need tighter tolerance than a fixed-threshold supervisor provides. The open-drain output allows wired-OR connection to other reset sources, and the active-low polarity matches the reset input of most MCUs, FPGAs, and SoCs. The 1 ms minimum reset timeout ensures the downstream logic sees a clean, glitch-free restart after a brownout or power-up sequence.
Package and mounting
Housed in a 16-pin SOIC (0.154-inch body width, 3.90 mm pitch), surface-mount only. The supplier device package is also 16-SOIC. This is a standard footprint for board-level power monitoring; no special layout beyond typical decoupling near the supply pins is required.
Lifecycle and sourcing posture
Listed as Active in the lifecycle record, with no NRND or EOL flags. The part is RoHS non-compliant, so verify your assembly house's exemption policy if you need lead-free processing.
