13 / 63 page  Figure 5. Soft-start procedure During the normal operation, a new soft-start cycle takes place in case of: 1. Thermal shutdown event 2. UVLO event 3. EN pin rising over VEN threshold. Please refer to Table 6. Electrical characteristics Figure 6. Soft-start phase with IOUT = 2.5 A 6.3 Undervoltage lockout The device implements the undervoltage lockout (UVLO) continuously sensing the voltage on the VCC pin, if the UVLO lasts more than 10 μs, the internal logic resets the device by turning off both LS and HS. After the reset, if the EN pin is still high, the device repeats the soft-start procedure. L6983 Undervoltage lockout DS13116 - Rev 2 page 13/63 |
