Power management integrated circuits (PMICs) are electronic components used to manage and direct the flow of power in electronic devices. These solutions come in a variety of shapes and sizes to accommodate different power configurations and applications. Among the most common PMIC applications are supervisors, which can provide advanced fault protection and reset control solutions. The DS1812-15+T&R is a supervisor IC designed to meet the needs of modern digital systems.

The DS1812-15+T&R is a dual-channel supervisor with an integrated watchdog timer that monitors all voltage levels for an out-of-tolerance condition. It is capable of resetting the system, both on-chip and off-chip, if any monitored voltage level is out of tolerance. Additionally, this device also supports Power OK indication as well as optional temperature monitoring and reset control. The integrated watchdog timer can be set up to trigger an internal reset pulse in case of unexpected behaviors. For example, if the processor generates no pulses on its reset pin, the watchdog timer can reset it to the expected state.

The main features of the DS1812-15+T&R are the dual-channel, reset-out control for microprocessor (CPU) reset and system reset control. Its dual-channel allows for reset control and monitoring independent of each other, providing more flexibility in high-power applications. This is especially useful when both the processor and system components operate at different voltages. and can be reset independently.

The internal reset-out control allows for reset of both processor and system components to a predetermined state when the reset input is activated. It supports a wide range of reset time intervals, from close to zero to over 100ms. This can help to prevent the system from locking up if there is an issue or issue with the processor. In addition, it supports both active low and active high reset control. This allows for significant flexibility in terms of system reset strategies.

The integrated watchdog timer provides a level of safety when the processor is operating at extreme temperatures or under heavy stress. If the processor generate no pulses on its reset pin, the watchdog timer can reset it to the expected state. This protection also helps prevent a system reset when the system is powered up, ensuring that the processor and other components maintain the expected state.

The DS1812-15+T&R is ideal for use in medical and industrial applications, where high reliability is required. It is also suitable for use in automotive electronics, where it can help protect critical systems from faults and maintain operating temperature levels. Furthermore, the device is also ideal for embedded applications, such as set-top boxes, routers and switches.

Overall, the DS1812-15+T&R is an ideal choice for application circuits requiring advanced fault protection and reset control. Its integrated watchdog timer helps protect the system from unexpected behaviors, while its reset-out control ensures the processor remains in a safe state. The device is suitable for a variety of applications, including automotive, medical and industrial. Furthermore, its robust design and integrated temperature monitoring provide assured operation even under extreme temperatures, giving designers the maximum level of security when using this device in their designs.
