TPS3306-25D

PMIC - Supervisors

Modern electronics require power management integrated circuits (PMICs) to ensure that components receive the right power at the right time. The Texas Instruments TPS3306-25D supervisor circuit is a type of PMIC designed for small, low-power applications. This device monitors its own power/voltage/current supply and provides additional features that are commonly used in consumer and handheld consumer electronics.

TPS3306-25D Features

The TPS3306-25D has several features that are beneficial to low-power applications. These can provide additional safety, performance and power savings to a device:

• Undervoltage lockdown
• Input power good/input power bad monitoring
• Reset input asserted/reset input not asserted monitoring
• Low power mode

TPS3306-25D Application Field and Working Principle

The TPS3306-25D is often used in applications such as industrial motor controls, HVAC systems, automotive systems and handheld consumer electronics. The device operates by monitoring both its own power/voltage/current inputs and other signals from the system. When the device senses a voltage, current or control signal that is outside its normal operating range, it can activate its low power mode, assert a reset output, or take other actions to safely shut down the system.

The TPS3306-25D also has built-in under-voltage-lockout (UVLO) protection, which prevents the circuit from operating when the voltage supply is below its minimum allowed threshold. This ensures that the system will not attempt to operate until the power/voltage/current supply stabilizes and is within the allowable range of the device. This also prevents the system from operating at an unsafe level due to a sudden power drop.

Conclusion

The TPS3306-25D is a supervisor circuit designed for small low-power applications. It can provide additional safety, performance and power savings with features such as undervoltage lockdown, input power monitoring, and a low power mode. This device is often used in systems such as industrial motor controls, HVAC systems, and handheld consumer electronics.
