Ta = +25°C Table 5 (Ta = +25°C unless otherwise specified) Item Symbol Condition Min. Typ. Max. Unit Test Condition Test Circuit Detection Voltage Overcurrent 1 detection voltage VDIOV1 − VDIOV1 − 0.015 VDIOV1 VDIOV1 + 0.015 V 1 1 Overcurrent 2 detection voltage *1 VDIOV2 − VDIOV2 − 0.100 VDIOV2 VDIOV2 + 0.100 V 1 1 Overcurrent 3 detection voltage VDIOV3 Overcurrent 3 detection function "available" 0.90 1.20 1.50 V 1 1 UVLO detection voltage VUVLO − 1.90 2.00 2.10 V 1 1 Release Voltage Overcurrent release voltage VRIOV VDD criteria, VDD = 3.5 V 0.7 1.2 1.5 V 1 1 Input Voltage, Operation Voltage Operation voltage between VDD pin and VSS pin VDSOP Output logic is determined *2 1.5 − 8 V − − Current Consumption Current consumption during normal operation IOPE VDD = 3.5 V, VVM = 0 V 1.0 3.5 7.0 μA 2 2 Current consumption during UVLO operation IUVLO VDD = VVM = 1.5 V 0.7 3.0 6.0 μA 2 2 Internal Resistance Internal resistance between VM pin and VSS pin RVMS VDD = VVM = 3.5 V 210 300 390 k Ω 3 3 Output Resistance (Active "L") DO pin resistance "L" RDOL VDD = VVINI = 3.5 V, VDO = 0.5 V 2.5 5 10 k Ω 4 4 Output Resistance (Active "H") DO pin resistance "L" RDOL VDD = 3.5 V, VVINI = 0 V VDO = 0.5 V 2.5 5 10 k Ω 4 4 Delay Time Overcurrent 1 detection delay time tDlOV1 − tDIOV1 × 0.6 tDIOV1 tDIOV1 × 1.4 ms 5 5 Overcurrent 2 detection delay time tDlOV2 − tDIOV2 × 0.6 tDIOV2 tDIOV2 × 1.4 ms 5 5 Overcurrent 3 detection delay time tDlOV3 Overcurrent 3 detection function "available" 168 280 392 μs 5 5 UVLO detection delay time tUVLO − 2.94 4.90 6.86 s 5 5 *1. Even if overcurrent 1 detection voltage and overcurrent 2 detection voltage are in the same range, VDIOV1 is lower than VDIOV2. *2. It indicates that DO pin output logic is determined. |
