It asserts a logic-low reset signal when the monitored voltage drops below the 1.665V threshold and keeps it low for a minimum of 140ms after the rail recovers. The push-pull output drives the reset input of an MCU, DSP, or FPGA directly — no external pull-up resistor needed. This part is built for surface-mount assembly in the compact SC-70-4 package, making it a fit for space-constrained boards in industrial control, telecom, and sensor interface designs where a clean power-on sequence matters. ## 1.665V threshold — the rail it watches The 1.665V threshold monitors a single voltage rail. This part triggers reset when the rail sags to 1.665V, which is early enough to prevent data corruption but late enough to avoid nuisance resets during normal ripple. ## 140ms reset timeout — why that number matters The 140ms minimum reset hold-off gives the power supply time to settle and the oscillator time to stabilize before the processor starts executing code. If your system uses a crystal oscillator with a slow start-up — common in low-power MCUs — this timeout covers the window. Shorter timeouts risk an incomplete power-up; longer ones delay the system ready signal. The 140ms figure is a middle-ground choice for most industrial and embedded designs. ## Active-low push-pull output — no external parts The active-low reset output (RESET bar) pulls low during fault and releases high when the supply is good. Because it is push-pull, it sources and sinks current — you connect it straight to the processor's reset pin without a pull-up resistor. This saves one component and one trace on a dense board. The totem-pole stage also drives the reset line cleanly, reducing noise coupling into the reset input. ## Lifecycle and sourcing — active, no LTB pressure The MAX6835HXSD3+T carries an Active product status with ROHS3 compliance. There is no last-time-buy notice or obsolescence risk on this line. For new designs or production replenishment, this part is available through independent distribution and is quoted to order against an RFQ.","metaTitle":"MAX6835HXSD3+T Simple Reset/Power-On Reset, 1.665V Threshold","metaDescription":"MAX6835HXSD3+T active-low push-pull reset IC with 140ms minimum timeout.

There is no end-of-life notice or last-time-buy schedule on this part. It is suitable for both new designs and ongoing production."},{"question":"What is the reset timeout of MAX6835HXSD3+T?","answer":"The reset timeout is a minimum of 140ms. This means the reset output stays low for at least 140ms after the monitored voltage rises above the 1.665V threshold, giving the system time to stabilize before the processor starts."},{"question":"Is MAX6835HXSD3+T active low or active high?","answer":"The reset output is active low.
