Product details

Active production — BOM-fit for 5V rail monitoring

The MAX815KCSA+: It monitors a single 5V supply rail with a 4.8V threshold, asserting a reset-low signal when the rail dips below that level. The push-pull, totem-pole output drives the reset input of an MCU or logic device directly without an external pull-up resistor. The 140ms minimum reset timeout holds the processor in reset long enough for the supply and oscillator to stabilise after a brownout or power-up event — a standard supervisory window for most 8- and 32-bit microcontrollers.

It is not qualified for automotive or extended industrial environments where -40°C to +85°C or +125°C is required. ROHS3 compliant per the lifecycle record, with no restricted-substance exemptions — no additional paperwork needed for EU or California market shipments.

Frequently asked questions

What is the reset timeout of MAX815KCSA+?

The reset timeout is 140ms minimum. This is the guaranteed pulse width the part asserts after the supply voltage rises above the 4.8V threshold, giving the downstream processor time to complete its power-on reset sequence.

Can MAX815KCSA+ be used in a 5V system with a 4.8V threshold?

Yes — the 4.8V threshold is designed for a nominal 5V supply rail. It asserts reset when the rail drops to 4.8V, which is approximately 4% below the nominal 5V level, providing early warning before the logic supply falls out of regulation.

Is MAX815KCSA+ RoHS compliant?

Yes, it is ROHS3 compliant — the highest level of RoHS compliance, covering all ten restricted substances including the four phthalates added in EU RoHS 2015/863.
