The push-pull, totem-pole output drives the reset input of an MCU, FPGA, or SoC directly — no external pull-up resistor needed. This part is built for the SC-70-3 (SOT-323) surface-mount footprint, which fits tight PCB layouts in industrial controllers, embedded systems, and portable equipment where board space is at a premium. ## Active-high reset — what it means for your processor choice This IC asserts a logic high on the reset output when the monitored voltage drops below the threshold. Not every processor expects an active-high reset — some want a low-going pulse. Check your target MCU or SoC reset polarity before committing the BOM. The push-pull output eliminates the external pull-up resistor, saving one component and one trace on dense boards. ## 100 ms timeout — standard window for most power-on sequences The 100 ms minimum reset timeout allows the power rail and oscillator to stabilise before the processor starts executing code. ## Lifecycle and sourcing The ADM1817-R22AKS-RL carries an active product status with ROHS3 compliance, so there is no last-time-buy or obsolescence pressure for current designs.","metaTitle":"ADM1817-R22AKS-RL Simple Reset/Power-On Reset, Active High","metaDescription":"ADM1817-R22AKS-RL is a simple reset/power-on reset IC from Analog Devices.
