It is a basic, no-frills supervisor for systems that need a clean, deterministic reset on power-up or during a brownout — think microcontroller-based boards, PLC I/O modules, or any embedded system where the processor must start from a known state. The reset output is active low with a push-pull (totem pole) driver, so it can directly drive the reset input of most MCUs without an external pull-up resistor. The reset timeout is a minimum of 140 ms, which gives the supply rail and oscillator time to stabilise before the processor starts executing code. The voltage threshold is 2.93 V. Operating temperature is 0°C to 70°C, so this part is intended for commercial indoor environments, not industrial or automotive under-hood use. It comes in an 8-SOIC surface-mount package (0.154\" body width, 3.90 mm width), a common footprint that fits standard PCB assembly flows. ## RoHS flag — what it means for your BOM This part is listed as RoHS non-compliant. If your assembly line or end-customer requires RoHS compliance (lead-free solder, no restricted substances), this part will not pass incoming inspection. For legacy or exempt military/industrial builds where leaded solder is still allowed, it is fine. Check your BOM's environmental requirements before committing. ## Lifecycle and sourcing reality That means it remains a viable choice for new designs and production runs, with no last-time-buy pressure. However, because it is RoHS non-compliant, some distributors may have limited stock or may not carry it at all. We source it through independent distribution, confirmed available to order against an RFQ.","metaTitle":"MAX709SCSA Simple Reset/Power-On Reset IC, 2.93V Threshold","metaDescription":"MAX709SCSA is an active-low push-pull reset supervisor IC from Maxim Integrated.
