6 / 26 page Analog Integrated Circuit Device Data 6 Freescale Semiconductor 34652 ELECTRICAL CHARACTERISTICS STATIC ELECTRICAL CHARACTERISTICS STATIC ELECTRICAL CHARACTERISTICS Table 3. Static Electrical Characteristics Characteristics noted under conditions 15 V ≤ VPWR ≤ 80 V and -40°C ≤ TA ≤ 85°C. All voltages are referenced to VIN unless otherwise noted. Characteristic Symbol Min Typ Max Unit POWER SUPPLY PIN (VPWR) Supply Voltage VPWR 15 — 80 V Supply Current, Device Enabled, Default Mode, Normal Operation (11) IIN — 900 1400 µA Undervoltage Lockout Threshold (UVLO) Rising Falling Hysteresis VUVLOR VUVLOF VUVLOHY 7.0 6.0 — 8.0 7.0 1.0 9.0 8.0 — V UNDERVOLTAGE CONTROL UV Threshold (Default) Rising Falling Hysteresis VUV(ON) VUV(OFF) VUVHY — — — 38 37 1.0 — — — V UV Comparator Threshold Rising Hysteresis VUVC VUVCHY — — 1.3 34 — — V mV UV Input Leakage Current IUVLG — — 1.0 µA Maximum Value of the Series Resistance Between UV and VPWR Pins — — — 500 k Ω OVERVOLTAGE CONTROL OV Threshold (Default) Rising Falling Hysteresis VOV(OFF) VOV(ON) VOVHY — — — 78 76 2.0 — — — V OV Comparator Threshold Rising Hysteresis VOVC VOVCHY — — 1.3 34 — — V mV OV Input Leakage Current IOVLG — — 1.0 µA Maximum Value of the Series Resistance Between UV and VPWR Pins — — — 500 k Ω Notes 11. The supply current depends on operation mode and can be calculated as follows: •Start-Up Mode: IIN = 539 µA + 548 µ * ICHG(A) + 216 µ * ILIM(A) + VPWR(V) / 460(kΩ) •Normal Mode: IIN = 539 µA + 240 µ * ILIM(A) + 288 µ * ILOAD(A) + VPWR(V) / 460(kΩ) •Overcurrent Mode: IIN = 539 µA + 612 µ * ILIM(A) + VPWR(V) / 460(kΩ) •Disable Mode: IIN = 539 µA + 240 µ * ILIM(A) + IDIS(µA) + VPWR(V) / 460(kΩ) |
