DS1812-10/T&R Datasheet/PDFThe DS1812-10/T&R is a supervisor IC designed for use in power management systems. It provides precision reset and reset signal monitoring, reset sequencing, caution or latch reset signal outputs, delay reset signal output and cycle punishment. This device is available in a SOP-8 package.
Application Field
The DS1812-10/T&R supervisor IC is best suited for applications that require a wide reset signal range, such as personal computers, imaging devices, and other demanding applications. It is suitable for use in 3.3V & 5V applications, as well as automotive and military applications.
It can also be applied in places that need reliable reset and monitoring for critical applications. Other applications include embedded systems, industrial and medical equipment, and networking.
Working Principle
The DS1812-10/T&R supervisor IC works by monitoring the incoming reset signal and providing active low assertion for reset. This device can also monitor power supply faults, system voltage dropping, and other critical factors.
The DS1812-10/T&R support various reset features, from simple passive reset monitoring to active reset generation and sequencing. Furthermore, it also offers pulse punishment and external reset input sources.
This device is also equipped with an adjustable reset output active time, reset de-assert delay time and supervisor operating supply current. Its adjustable trip point is between 1.425V - 3.63V. In addition, the device has tolerance active time and reset de-assert time of ±10%.
Moreover, the DS1812-10/T&R is able to generate reset using external signals. It supports both edge triggered and level triggered reset inputs. The pulse punishment feature ensures that even if the reset signal drops, the IC keeps resetting in a certain period.
Conclusion
The DS1812-10/T&R is a power management supervisor IC that offers precision reset and reset signal monitoring, reset sequencing, caution or latch reset signal outputs, delay reset signal output and cycle punishment. This device is most suitable for applications that require a wide reset signal range, such as personal computers, imaging devices, embedded systems, industrial and medical equipment, networking, and other demanding applications.
