Texas Instrument’s application note about how undervoltage lockout (UVLO) protect devices from undefined behavior. Link here (PDF)

Many integrated circuits include an undervoltage lockout (UVLO) function to disable the device at low supply voltages. Below the minimum supply voltage the function and performance of a device may be undefined, making it impossible to predict system behavior. This application note explains how to correctly understand the undervoltage lockout specification in the data sheets of TI’s Display Power products.
