Functional Description

Over Voltage Protection (OVP)

The OVP is triggered if V

FB > 1.5x VEAP sustained 5us.

When OVP is activated, the uP9511 turns on all low-side

MOSFETs and turns off all high-side MOSFETs. The over

voltage protection is a latch-off function and can only be

reset by 5VCC re-POR or EN restart.

Under Voltage Protection (UVP)

The under voltage protection is triggered if V

FB < 0.5 x VEAP

sustained 5us. When UVP is activated, the uP9511 turns

off all high-side and low-side MOSFETs. The under voltage

protection is a latch-off function and can only be reset by

5VCC re-POR or EN restart.

Over Temperature Protection (OTP)

The uP9511 monitors the temperature of itself. If the

temperature exceeds typical 150oC, the uP9511 is forced

into shutdown mode. The over temperature protection is a

latch-off function and can only be reset by 5VCC re-POR

or EN restart.
