The TPS3808G25DBVR is an IC (Integrated Circuit) component manufactured by Texas Instruments. It is a voltage supervisor and monitoring device designed to ensure the reliable operation of microprocessors, microcontrollers, and other digital systems. The IC provides various key features that make it popular in applications where power supply supervision is critical. Here is an overview of the TPS3808G25DBVR along with its significant features:
1. Voltage Monitoring: The TPS3808G25DBVR supervises the system's power supply voltage, detecting undervoltage and overvoltage conditions. It monitors a voltage range of 2.5V, making it suitable for systems powered by batteries, LDOs, or switching regulators.
2. Reset Generation: It generates a reset signal when the monitored voltage goes below or rises above the configured threshold levels. This feature ensures that the system remains in a known state during voltage fluctuations or power supply events.
3. Programmable Thresholds: The IC allows customers to program the undervoltage and overvoltage thresholds through external resistor dividers. This flexibility enables designers to set the voltage limits as per their system requirements.
4. Manual Reset Input: The TPS3808G25DBVR includes a manual reset input (MR), which can be used to assert a system reset externally. When this input is pulled low or connected to GND, it forces the reset output (RESET) to assert irrespective of the voltage conditions
