Power Management Integrated Circuits (PMICs) are specialized semiconductor devices that combine a blend of analog and digital circuits. They form a bridge between a power source and the device being powered, providing control and supervision over the delivery and consumption of power. Within the group of PMICs, the sub category of supervisors exist as a specialized type. Supervisors provide an additional layer of monitoring by adding a dedicated set of safety controlled functions such as voltage monitoring and resetting.

The TLV810RDBZR is a supervisor, a specialized type of PMIC, from Texas Instruments. It is suitable for low voltage systems with up to 1.8-V VCC. The TLV810RDBZR belongs to the general family of reset supervisors, designed with detailed safety and fault management features, supporting a variety of configurable reset functions and durations to satisfy a wide range of applications.

Application Fields

The TLV810RDBZR has several applications including use in low voltage systems where efficient and safe power management is required. It particularly excels in applications where detecting a low voltage level is key, such as in monitoring battery voltages. Other applications for the TLV810RDBZR include providing various reset options for safety protection, such as time out protection and manual reset, and providing certain protection functions when certain overvoltages are encountered. This PMIC supervisor is not only active at the low voltage level but also on a higher voltage level, as certain applications do not require a low voltage reset function.

Working Principle

The TLV810RDBZR functions by monitoring a system’s voltage level and outputting a reset signal when the voltage level drops below a user-defined level. It contains two comparators entered in an open drain configuration. Inputs VCC1 and VCC2 are used to monitor the voltage level. The TLV810RDBZR can be configured by the voltage regulator or the processor. The TLV810RDBZR also works by providing two reset outputs that can be configured either to be active-low or active-high. The output can be controlled internally by the voltage regulator or by the processor.

Integrated onto the TLV810RDBZR is a Level 1 reset supervisor circuitry that helps to protect against voltage transients from the power supply, preventing system crashes. This supervisor circuitry contains an on-chip setable and latchable reset circuit, with configurable reset time-outs and active reset output control. This Level 1 reset supervisor also provides a pushbutton input that allows for manual resetting of the device when necessary.

The safety of system operating voltages is also improved with the TLV810RDBZR by providing higher than usual voltage monitor thresholds. Also included is on-chip temperature monitoring with configurable output status and an integrated voltage reference. This voltage reference allows for an externally monitored reset input that can perform user-defined functions based on the system’s voltage level.

All in all, the TLV810RDBZR is a great choice when the system requires the ability to perform reset functions under low and high voltage conditions. It is designed to protect the system from voltage transients and provide a reset function when the voltage level is too low. Its Level 1 reset supervisor provides user-defined reset configurations, on-chip temperature monitoring and configurable reset outputs.
