Protection Methods PMU Shutdown Delay Time Reset Method SYS UVLO SYS < 1.5V PMU Shutdown. No-delay EN1234 pin set to low or SYS > 2.1V OVP VDDM > 6V Automatic reset at VDDM < 5.85V 100ms VDDI power reset or EN1234 pin set to low VDDI UVLO VDDM < 2.4V PMU Shutdown. No-delay VDDI power reset or EN1234 pin set to low Current Limit N-MOSFET peak current > 3A N-MOSFET off, P-MOSFET off. Automatic reset at next clock cycle. 100ms VDDI power reset or EN1234 pin set to low PVD1 OVP PVDD1 > 6V N-MOSFET off, P-MOSFET off. No-delay VDDI power reset or EN1234 pin set to low PVD1 UVP --1 PVDD1 < (VSYS − 0.8V) or PVDD1 < 1.28V after soft-start end. N-MOSFET off, P-MOSFET off. 100ms VDDI power reset or EN1234 pin set to low PVD1 UVP --2 After pre-charge (PVD1 UVP-2 : FB1 < 0.4V after pre-charge) N-MOSFET off, P-MOSFET off No-delay VDDI power reset or EN1234 pin set to low CH1 Step-Up PVD1 Over Load (OL) Target − 0.6V Target Voltage is defined in A4.VOUT1 [3:0] PMU Shutdown when OL occur each cycle until 100ms. 100ms VDDI power reset or EN1234 pin set to low Current limit Both P-MOSFET (PVD2 − LX2A) and N-MOSFET (LX2B − GND) peak current > 2A N-MOSFET off, P-MOSFET off. Automatic reset at next clock cycle. 100ms VDDI power reset or EN1234 pin set to low VO2 OVP PVDD1 > 6V N-MOSFET off, P-MOSFET off. No-delay VDDI power reset or EN1234 pin set to low FB2 UVP FB2 < 0.4V after soft-start end. N-MOSFET off, P-MOSFET off. No-delay VDDI power reset or EN1234 pin set to low CH2 Step-Up/Down FB2 Over Load Target − 0.1V (Target voltage is the chosen one in A4.FB2 [2:0]) PMU Shutdown when OL occur each cycle until 100ms. 100ms VDDI power reset or EN1234 pin set to low Current limit P-MOSFET peak current > 1.8A N-MOSFET off, P-MOSFET off. Automatic reset at next clock cycle. 100ms VDDI power reset or EN1234 pin set to low FB3 UVP FB3 < 0.4V after soft-start end. N-MOSFET off, P-MOSFET off. No-delay VDDI power reset or EN1234 pin set to low CH3 Step-Down FB3 Over Load Target − 0.1V (Target voltage is the chosen one in A5.FB3 [2:0]) PMU Shutdown when OL occur each cycle until 100ms. 100ms VDDI power reset or EN1234 pin set to low |
