5 / 42 page  2016 Microchip Technology Inc. DS20005610A-page 5 MIC4607 DC CHARACTERISTICS (Note 1, 2) Electrical Characteristics: Unless otherwise indicated, VDD = VxHB = 12V; VEN = 5V; VSS = VHS = 0V; No load on xLO or xHO; TA = 25°C; unless noted. Bold values indicate –40°C< TJ < +125°C. Parameters Sym. Min. Typ. Max. Units Conditions Supply Current VDD Quiescent Current IDD — 390 750 μA xLI = xHI = 0V VDD Shutdown Current IDDSH — 2.2 10 μA xLI = xHI = 0V; EN = 0V with HS = floating — 58 150 xLI = xHI = 0V ; EN = 0V; HS = 0V VDD Operating Current IDDO — 0.6 1.5 mA f = 20 kHz Per Channel xHB Quiescent Current IHB — 20 75 μA xLI = xHI = 0V or xLI = 0V and xHI = 5V Per Channel xHB Operating Current IHBO — 30 400 μA f = 20 kHz xHB to VSS Current, Quiescent IHBS — 0.05 5 μAVxHS = VxHB = 90V xHB to VSS Current, Operating IHBSO — 30 300 μA f = 20 kHz Input (TTL: xLI, xHI, xPWM, EN) (Note 3) Low-Level Input Voltage VIL —— 0.8 V — High-Level Input Voltage VIH 2.2 —— V — Input Voltage Hysteresis VHYS 0.1 — V — Input Pull-Down Resistance RI 100 300 500 kΩ xLI and xHI Inputs (-1 Version) 50 130 250 xPWM Input (-2 Version) Undervoltage Protection VDD Falling Threshold VDDR 3.8 4.4 4.9 V — VDD Threshold Hysteresis VDDH — 0.25 — V — xHB Falling Threshold VHBR 4.0 4.4 4.9 V — xHB Threshold Hysteresis VHBH — 0.25 — V — Overcurrent Protection Rising Overcurrent Threshold VILIM+ 175 200 225 mV (VILIM+ – VILIM–) ILIM to Gate Propagation Delay tILIM_PROP — 70 — ns VILIM+ = 0.5V peak Fault Circuit FLT/ Output Low Voltage VOLF — 0.2 0.5 V VILIM = 1V; IFLT/ = 1 mA Rising DLY Threshold VDLY+ — 1.5 — V — DLY Current Source IDLY 0.3 0.44 0.6 μAVDLY = 0V Fault Clear Time tFCL — 670 — μsCDLY = 1 nF Bootstrap Diode Low-Current Forward Voltage VDL — 0.4 0.70 VIVDD-xHB = 100 μA High-Current Forward Voltage VDH — 0.8 1 VIVDD-xHB = 50 mA Note 1: “x” in front of a pin name refers to either A, B or C phase. (e.g. xHI can be either AHI, BHI or CHI). 2: Specification for packaged product only. 3: VIL(MAX) = maximum positive voltage applied to the input which will be accepted by the device as a logic low. VIH(MIN) = minimum positive voltage applied to the input which will be accepted by the device as a logic high. 4: Guaranteed by design. Not production tested. |
