TLV809I50DBZR belongs to power management integrated circuit (PMIC) - Supervisors category and is a three-terminal integrated voltage supervisor optimized for low-power micro-controller systems and embedded application processors. This device features an integrated reference and a shunt-regulated comparator for supply voltage supervision, a voltage-adjustable comparator for dynamic supply voltage monitoring, and an integrated voltage-detector reset circuit.

The integrated reference and comparator provides accurate and stable monitoring of power supplies enabling reliable system power up and down operations, while the voltage-adjustable output monitors dynamic supply voltage. In addition, the integrated reset circuit allows the system to respond quickly to out-of-range conditions, detecting reset events and releasing reset within typical times of 2ms and 15ms respectively.

The TLV809I50DBZR is an adjustable 3-Terminal voltage supervisor, which features an adjustable input voltage range, adjustable output voltage, and adjustable reset pulse width. This provides extremely efficient power performance under both normal and dynamic supply conditions, providing superior protection against out-of-range conditions. It also offers an active-low/active-high reset output, adjustable reset delay after out-of-range conditions, and provides adjustable input voltage comparator thresholds. The voltage supervisor also integrates hysteresis, providing improved system noise immunity and reliable voltage monitoring.

The TLV809I50DBZR applications mainly include automotive, industrial, communications, and consumer electronics. Since it is designed to provide reliable power up and down signalling to the microcontroller and embedded application processors, it is used in many automotive and industrial applications. Specifically, they are used in order to ensure that the system is monitored against out-of-range conditions, such as high/low supply voltage, or voltage change at a rate exceeding the specified limit.

The working principle of the TLV809I50DBZR is quite straightforward; an input voltage is applied to the voltage supervisor, which is then compared with the reference voltage. If this reference voltage is exceeded, a reset pulse is generated, allowing the system to reset. The result is a system that is more robust and power efficient, in order to provide the expected performance under any operating conditions.

Overall,TLV809I50DBZR Voltage Supervisors are an excellent choice for any system that needs to ensure reliable and precise power management. Their integrated reference, integrated comparator and adjustable reset delay ensure superior protection against out-of-range conditions and provides reliable system power up and down operations. Moreover, they are compatible with a wide range of automotive, industrial, communications and consumer electronics applications, leaving users to benefit from superior operating performance and efficiency.
