The MAX809T SOT-23 RoHS manufactured by Youtai is an electronic part that serves as a microprocessor and microcontroller supervisor. It helps to protect electronic components from any overvoltage or thermal anomalies. It has an adjustable reset voltage that can be set from 2.31V to 5.5V for system protection. The MAX809T has two reset output options, a push-pull active-low reset and an open drain active-low reset. Its active-low reset is guaranteed to assert for VDD down to 1V. It also has a power-on reset pulse width that is adjustable from 10ms to 1.1s. Furthermore, it has a logic output selectable between CMOS or open drain and can be triggered by an external reset. The device is RoHS compliant and requires no external components to function properly.
