描述

The series of DIO6820 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 DIO6820 outputs an active-low reset pulse signal (/RST). For the DIO6821/C, the /RST pin outputs a low pulse signal with a fixed time. For the DIO6820, the /RST pin outputs a low pulse signal until either of the PBx inputs is released. The DIO6820 has an active-low and open-drain output that can be wire-ORed with other open-drain devices. The DIO6820 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 DIO6820 is a good choice for a micropower solution for system resetting needs.
