TPS2101DBVT is a power management integrated circuit (PMIC), more specifically an over-current-protection (OCP) controller with an ideal diode. It is designed to reliably protect consumer electronic devices and components against harmful over-current events, while significantly reducing power consumption when compared to traditional protection solutions.

The TPS2101DBVT operates in a “mode-of-operation” selection. When the input voltage is above the trip threshold point, it behaves as a MOSFET switch, that is, it boosts the current and voltage to the load. On the other hand, when the load current becomes lower than a selected level, the TPS2101DBVT stops boosting the voltage, and behaves like an ideal diode, allowing the current to flow in only one direction, protecting the load from any over-currents.

The TPS2101DBVT is an I2C slave device that can be programmed through the I2C bus. The TPS2101DBVT has two selectable options to set the OCP threshold level: relative mode and absolute mode. Relative mode sets the threshold current relative to an “initial value” programmed with a voltage waveform applied to the dedicated pins. Alternately, absolute mode sets the threshold current directly through the I2C bus. This feature eliminates the need for a waveform generator, making the configuration process easy and fast.

An additional feature of the TPS2101DBVT is its safety timer. This feature can be programmed through the I2C bus by setting the TPS2101DBVT in mode selection. If a power-on transient exceeds the overload threshold, the TPS2101DBVT will automatically shut down the circuit and reset itself after a programmed time interval. This timer protects the load from continuous overload and restarting of the circuit.

The TPS2101DBVT also includes an overtemperature (OT) detection circuit. This feature monitors the junction temperature inside the device itself and shuts down the circuit in the event of an overtemperature condition. This feature helps protect the circuit from thermal-induced stress.

The TPS2101DBVT is accurate, reliable and power-efficient and is suitable for devices in the consumer electronics, telecom, industrial and automotive markets which require reliable over-current protection or ideal diode solutions. It is also designed to have a very low standby power, which makes it suitable for always-on applications.

Overall, the TPS2101DBVT is an over-current protection controller \ with ideal diode solutions that helps protect consumer electronic devices and components against over-current events while reducing power consumption. It is reliable, accurate, and power-efficient and is suitable for consumer electronics, telecom, industrial, and automotive markets.
