DIO6821C

The series of DIO6821C is low-current, ultra-small, push-button controller with single or dual inputs. These devices, which has a long setup delay time, provide the intended system reset and avoid the reset because of short push-button closures or unintended press action. This reset output can be programmed by TS pin or depends on inputs. If both inputs (PB1 and PB2) are pulled low, the DIO6821C output an active-low reset pulse signal (/RST). For the DIO6821C, the /RST pin outputs a low pulse signal with a fixed time. The DIO6821C has an active-low and open-drain output that can be wire-ORed with other open-drain devices. The DIO6821C has a wide operating voltage from 1.6 V to 6.6 V and operation under the -40°C to +125°C temperature range. The DIO6821C is a good choice for a micropower solution for system resetting needs.
