It is designed for systems where a backup battery must maintain memory or real-time clock functions during a main power loss — think industrial controllers, PLCs, and embedded instrumentation that need clean power-fail sequencing. The reset output is active-low, push-pull (totem pole), so it drives the processor reset pin directly without an external pull-up resistor. The reset timeout is a minimum of 140 ms, which gives the supply rail time to stabilise after a brownout before the processor is released from reset. The voltage threshold is 4.65 V. The operating temperature range is -40°C to 85°C. ## Package and mounting — through-hole for prototyping and rework Housed in an 8-pin DIP package (0.300\" body width, 7.62 mm pitch), the MAX694EPA is through-hole mount. That makes it a natural choice for breadboard prototyping, socketed evaluation, or replacing a failed supervisor on a legacy PCB where a DIP footprint already exists. The 8-PDIP supplier device package is the same physical part — just the manufacturer's internal code for the plastic DIP variant. ## Lifecycle and sourcing — active, but watch the RoHS flag The part is RoHS non-compliant. For legacy builds or contracts with RoHS exemptions, it remains a valid choice. ## Marking and provenance — what to check on incoming inspection Given the part is through-hole and still active, counterfeit risk is lower than for obsolete or high-volume surface-mount parts, but it is not zero. On a MAX694EPA, the top-side marking should read 'MAX694EPA' in a consistent font — any sanding, re-marking, or laser-etch mismatch across a reel is a red flag. Date-code laser etch on the body should match the manufacturer's plant format for the week claimed. If you are buying from the independent channel, request lot-trace documentation and, for large quantities, consider a decap X-ray to verify the die matches Maxim's known layout for this part.","metaTitle":"MAX694EPA Battery Backup Circuit, Active-Low Reset, 140ms","metaDescription":"Maxim MAX694EPA battery backup supervisor IC.

This means the reset output stays low for at least 140 ms after the supply voltage rises above the 4.65 V threshold, giving the rail time to stabilise before the processor starts."},{"question":"Is MAX694EPA compatible with 5V systems?","answer":"Yes, the 4.65 V threshold is designed for 5 V nominal supplies.
