5 / 39 page Micrel, Inc. MIC2164/-2/-3/C September 2010 5 M9999-091310-D Electrical Characteristics (4) (Continued) VBST − VLX = 5V; TA = +25°C, unless noted. Bold values indicate −40°C ≤ TJ ≤ +125°C. Parameter Condition Min. Typ. Max. Units Maximum Duty Cycle (9) MIC2164/ MIC2164C MIC2164-2 MIC2164-3 87 74 66 % Minimum Duty Cycle Measured at DH, VFB = 1V 0 % FET Drives DH, DL Output Low Voltage ISINK = 10mA 0.1 V DH, DL Output High Voltage ISOURCE = 10mA VIN − 0.1V or VBST − 0.1V V DH On-Resistance, High State 2.1 3.3 Ω DH On-Resistance, Low State 1.8 3.3 Ω DL On-Resistance, High State 1.8 3.3 Ω DL On-Resistance, Low State 1.2 2.3 Ω LX Leakage Current VLX = 28V, VIN = 5.5V,VBST = 33.5V 50 µA HSD Leakage Current VLX = 28V, VIN = 5.5V,VBST = 33.5V 20 µA Thermal Protection Over-Temperature Shutdown 155 °C Over-Temperature Shutdown Hysteresis 10 °C Shutdown Control EN Logic Level Low 3V < VIN <5.5V 0.4 0.8 V EN Logic Level High 3V < VIN <5.5V 0.9 1.2 V EN Pull-Up Current 50 µA Note: 1. Exceeding the absolute maximum rating may damage the device. 2. The device is not guaranteed to function outside its operating rating. 3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF. 4. Specification for packaged product only. 5. The application is fully functional at low IN (supply of the control section) if the external MOSFETs have enough low voltage VTH. 6. The current will come only from the internal 100kΩ pull-up resistor sitting on the EN Input and tied to IN. 8. Measured in test mode. 9. Measured at DH. The maximum duty cycle is limited by the fixed mandatory off time TOFF of typical 363ns. |
