The DS1233DZ-10+T&R is a micro-power supervisor that integrates multiple functions of power-on reset (POR), power supply monitoring (PSM), low-battery detect (LBD), and system reset functions. It is optimally designed for applications with power-up and power-down events such as for digital systems and embedded control systems. As a supervisor, the DS1233DZ-10+T&R is integrated together with an external micro-power oscillator/external battery to monitor, confirm and assert various micro-power reset/watchdog signals.

Application Field of DS1233DZ-10+T&R

The application field of DS1233DZ-10+T&R is extensive and widespread. It can be used in microprocessor-based systems, system control and instrumentation products, such as hand-held instruments, banking terminals, and printer control circuit, etc. It can also be applied to monitor the system power-on sequence and protect against power-on surge/spikes and system under-/overvoltage conditions. Furthermore, as an external battery reset operation, it can be used to maintain the accuracy of RTC and other critical user data under system power-loss conditions. The DS1233DZ-10+T&R is most suitable for any cost-sensitive, low-power system.

Working Principle of DS1233DZ-10+T&R

The DS1233DZ-10+T&R provides a combination of power-on reset (POR), power supply monitor (PSM), and low-battery detection (LBD) functions in one system-level supervisor circuit. Since the DS1233DZ-10+T&R does not use an internal oscillator, the timing requirements from POR to PSM to LBD are established externally with an external signal source. This allows for better distribution of the power-on and power-down responsibilities among the various integrated circuits within the system.

The DS1233DZ-10+T&R provides a reset function that ensures the reliable operation of the system by monitoring a variety of system levels. It has a power-on reset input that is asserted whenever power is applied to the circuit and is used to reset the system logic. The power-on reset may also be used to indicate the occurrence of power failures to prevent loss of data or erroneous operation. The power supply monitor input is used to monitor the various power supply voltages when the power-on reset is low. It will assert a reset pulse if an undervoltage condition is detected. Finally, the low-battery detect (LBD) input is used to detect and indicate an external battery Low condition.

Conclusion

The DS1233DZ-10+T&R is an ideal supervisor for system-level reset/watchdog applications. It is featured as an integrated system-level supervisor with power-on reset, power supply monitoring and low-battery detect functions. As an external battery reset applications, it provides backup reset functions for embedded applications with low power requirements. In the application field, the DS1233DZ-10+T&R are widely used in microprocessor-based systems, system control and instrumentation products, such as hand-held instruments, banking terminals, and printer control circuit, etc. Overall, the DS1233DZ-10+T&R is a reliable and cost-effective solution for various power monitoring and reset applications.
