3 / 32 page –3– REV. C ADMC328 VOLTAGE REFERENCE Parameter Min Typ Max Unit Conditions/Comments Voltage Level (VREF) 2.40 2.50 2.60 V 2.45 2.50 2.55 V TA = 25 °C to 125°C SOIC1 Output Voltage Drift 35 ppm/ °C NOTES 1This specification for voltage level (V REF) is for SOIC package only, at specified temperature range. Specifications subject to change without notice. ISENSE AMPLIFIER–TRIP Parameter Min Typ Max Unit Conditions/Comments ISENSE Amplifier Gain, G 1 –5.7 –5.1 –4.7 ISENSE = –0.4 V to 0.0 V ISENSE Amplifier Offset, VO 2 80 155 240 mV ISENSE Offset Variation 3 0.14 %/ °C Overcurrent Trip Voltage, (VTRIP) 4 –0.64 –0.53 –0.45 V ISENSE Leakage Current –320 +10 µAI SENSE = –0.4 V to VDD NOTES 1I SENSE Amplifier Output to ADC is V3 = G × I SENSE + VO. 2V O is effective ADC input with zero voltage at I SENSE pin. This value may be compensated in software. 3Offset voltage increases with temperature. 4Input I SENSE voltage at which PWM shutdown is generated. Specifications subject to change without notice. POWER-ON RESET Parameter Min Typ Max Unit Conditions/Comments Reset Threshold (VRST) 3.2 3.7 4.2 V Hysteresis (VHYST) 100 mV Reset Active Timeout Period ( t RST) 3.2 1 ms NOTES 1216 CLKOUT Cycles. Specifications subject to change without notice. |
