PMIC - Supervisors are used to provide a secure power management interface and enable platforms to function. One of these is the S-1000N36-N4T1G, a device used to provide a voltage supervisor in certain applications. By understanding the application fields and its working principle, one can appreciate the use of the S-1000N36-N4T1G and its design considerations.

Application field of the S-1000N36-N4T1G

The S-1000N36-N4T1G is used as a voltage supervisor for various applications. It allows for applications using power management to detect low or high voltage conditions in a system. It monitors voltages over a wide range that can reduce cost for the platform and allow for the safe shutdown when included in applications using large scale power supplies. This device has a smaller footprint of 8-MILs and can be used for many applications such as computers, consumer electronics, telecoms, and other devices that require a stable power supply. It also includes active power-save features, e.g., LOGIC Shutdown, SMPS Driver Shutdown, and SMPS Brownout detect to enable better power saving modes. This device also has optional watchdog timer and manual reset support.

Working Principle of the S-1000N36-N4T1G

The S-1000N36-N4T1G is based on the TCU3802 voltage supervisor IC. This IC contains a low voltage detector (LVD) and a high voltage detector (HVD) to monitor voltages in the normal operating range. The voltage supervisor also includes a power-on-reset (POR) circuit to ensure proper device startup. When enabled, the POR provides an internal reset signal for the system when the device is powered-up.

The TCU3802 LVD continuously monitors the incoming power supply voltage. When the voltage falls below the adjustable overvoltage (OV) limit, the LVD asserts a reset signal, triggering a system or device reset. This reset signal can be enabled externally using an external adapter, or via a dedicated pin designed for the purpose. The TCU3802 also includes an internal die temperature sensor which, when enabled, will reset the system if the die temperature exceeds the operation temperature limit.

The TCU3802 also includes a manual reset circuitry to provide a user configurable reset signal. This signal can be forced via a dedicated reset pin or by setting a specific voltage on the dedicated reset pin. This additional reset feature is useful to provide a means to reset the system in the event of a failure or fault condition.

The TCU3802 also includes a power-switch detector, which asserts a signal when the power switch is off. This signal can be used for external signal detection. The TCU3802 also provides an active pull-up signal which can be connected to an external circuit or input to alert the device when the power switch is off.

Finally, the TCU3802 includes an active power-saving mode and an internal trickle charger to reduce the power consumption of the system while still maintaining the voltage. This power-saving mode allows the device to detect low voltage conditions and automatically switch to another power saving mode.

Conclusion

The S-1000N36-N4T1G is a powerful voltage supervisor designed for various applications. It monitors voltages over a wide range of input voltages and enables the platform to provide a secure power management interface when integrated into the system. Through its active power-save features, such as LOGIC Shutdown, SMPS Driver Shutdown, and SMPS Brownout detect, it can reduce the power consumption of the system and enable better power saving modes. With its wide range of application fields, it provides for various purposes and can provide a reliable source of voltage for the system.
