SLVSHL0B June 2024 – July 2024 TPSM81033
ADVANCE INFORMATION
The TPSM81033 has a built-in undervoltage lockout (UVLO) circuit to ensure the device working properly. When the analog input voltage (AVIN) is above the UVLO rising threshold of 1.7V (typical), the TPSM81033 can be enabled to boost the output voltage. The device is disabled when the falling voltage at the AVIN pin trips the UVLO falling threshold, which is 1.6V (typical). A hysteresis of 100mV (typical) is added so that the device cannot be enabled again until the input voltage exceeds 1.7V (typical). This function is implemented to prevent the device from malfunctioning when the input voltage is between UVLO rising and falling threshold.
