32 / 47 page  USB4715 DS00002514B-page 32 2022 Microchip Technology Inc. and its subsidiaries 9.3 Package Thermal Specifications 9.4 Power Consumption This section details the power consumption of the device as measured during various modes of operation. Power dis- sipation is determined by temperature, supply voltage, and external source/sink requirements. Note: The rise time for the 3.3V supply can be extended to 100ms max if RESET_N is actively driven low, typi- cally by another IC, until 1 μs after all supplies are within operating range. TABLE 9-1: PACKAGE THERMAL PARAMETERS Symbol °C/W Velocity (Meters/s) JA 28 0 25 1 JB 15 0 JT 0.2 0 JC 2.4 0 Note: Thermal parameters are measured or estimated for devices in a multi-layer 2S2P PCB per JESDN51. TABLE 9-2: DEVICE POWER CONSUMPTION Description Typical Current (mA) Maximum Current (mA) Reset Current (mA) 0.40 3.60 Suspend Current (mA) 0.40 3.60 Idle 56 67 Active Operation (4 Hi-Speed Devices) 148 167 Active Operation (1 Hi-Speed, 1 Full-Speed Device) 73 74 Active Operation (2 Hi-Speed, 2 Full-Speed Devices) 97 98 Active Operation (2 Hi-Speed, 1 Full-Speed Device) 96 97 Active Operation (1 Full-Speed Device) 57 58 Active Operation (4 Full-Speed Devices) 64 65 Active Operation (1 Hi-Speed Device) 73 74 Active Operation (2 Hi-Speed Devices) 102 103 Active Operation (3 Hi-Speed Devices) 122 123 Active Operation (FlexConnect enabled on 1 port, Hi-Speed data transfer on 4 ports) 149 150 |
