10 / 45 page Analog Integrated Circuit Device Data 10 Freescale Semiconductor 33911 ELECTRICAL CHARACTERISTICS STATIC ELECTRICAL CHARACTERISTICS HIGH SIDE OUTPUT HS1 PIN (HS1) Output Drain-to-Source On resistance TJ = 25°C, ILOAD = 50mA; VSUP > 9.0V TJ = 150°C, ILOAD = 50mA; VSUP > 9.0V (27) TJ = 150°C, ILOAD = 30mA; 5.5V < VSUP < 9.0V (27) RDS(ON) – – – – – – 7.0 10 14 Ω Output Current Limitation(28) 0V < VOUT < VSUP - 2.0V ILIMHS1 60 120 250 mA Open Load Current Detection(29) IOLHS1 – 5.0 7.5 mA Leakage Current -0.2V < VHS1 < VS2 + 0.2V ILEAK – – 10 µA Short-circuit Detection Threshold(30) 5.5V < VSUP < 27V VTHSC VSUP -2 – – V Over-temperature Shutdown(31), (36) THSSD 150 165 180 °C Over-temperature Shutdown Hysteresis(36) THSSD_HYS – 10 – °C LOW SIDE OUTPUTS LS1 AND LS2 PINS (LS1, LS2) Output Drain-to-Source On resistance TJ = 25°C, ILOAD = 150mA, VSUP > 9.0V TJ = 125°C, ILOAD = 150mA, VSUP > 9.0V TJ = 125°C, ILOAD = 120mA, 5.5V < VSUP < 9.0V RDS(ON) – – – – – – 2.5 4.5 10 Ω Output Current Limitation (32) 2.0V < VOUT < VSUP ILIMLSX 160 275 350 mA Open Load Current Detection(33) IOLLSX – 8.0 12 mA Leakage Current -0.2V < VOUT < VS1 ILEAK – – 10 µA Active Output Energy Clamp IOUT = 150mA VCLAMP VSUP +2 – VSUP +5 V Short-circuit Detection Threshold(34) 5.5V < VSUP < 27V VTHSC 2.0 – – V Over-temperature Shutdown(35), (36) TLSSD 150 165 180 °C Over-temperature Shutdown Hysteresis(36) TLSSD_HYS – 10 – °C Notes 27. This parameter is production tested up to TA = 125°C and guaranteed by process monitoring up to TJ = 150°C. 28. When over-current occurs, the High Side stays ON with limited current capability and the HS1CL flag is set in the HSSR . 29. When open Load occurs, the flag (HS1OP) is set in the HSSR . 30. When short-circuit occurs and if the HVSE flag is enabled, HS1 automatically shut down. 31. When over-temperature Shutdown occurs, the High Side is turned off. All flags in HSSR are set. 32. When over-current occurs, the corresponding Low Side stays ON with limited current capability and the LSxCL flag is set in the LSSR . 33. When open load occurs, the flag (LSxOP) is set in the LSSR. 34. When short-circuit occurs and if the HVSE flag is enabled, both LS automatically shut down. 35. When over-temperature shutdown occurs, both Low Sides are turned off. All flags in LSSR are set. 36. Guaranteed by characterization but not production tested Table 3. Static Electrical Characteristics (continued) Characteristics noted under conditions 5.5V ≤ V SUP ≤ 18V, -40°C ≤ TA ≤ 125°C for the 33911 and -40°C ≤ TA ≤ 85°C for the 34911, unless otherwise noted. Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal conditions, unless otherwise noted. Characteristic Symbol Min Typ Max Unit |
