7 / 56 page  TPS40400 www.ti.com SLUS930A – APRIL 2011 – REVISED JULY 2011 ELECTRICAL CHARACTERISTICS (continued) Unless otherwise stated, these specifications apply for –40°C ≤ TJ ≤ 125°C, VDD= 12 Vdc, FREQUENCY_SWITCH = 600 kHz PARAMETER TEST CONDITIONS MIN TYP MAX UNIT MEASUREMENT SYSTEM tIDLY Read delay time (9) 153 192 231 μs IRES Current measurement resolution (LSB) (10) (11) 122 μV IRNG Current measurement range(11) (12) –45 110 mV IACC Gain accuracy(13) –3% 3% IOFST Offset –3 3 mV VOUT(res) VOUT measurement resolution (LSB) 15.625 mV VOUT(rng) VOUT voltage measurement range 0 14 V VOUT(gain) Gain accuracy(13)(14) –2 2 LSB VOUT(gain_adj) Gain adjustment range through PMBus –10% 10% VOUT(ofst) Offset(13)(14) –3% 3% VOUT(ofst_adj) Gain adjustment range through PMBus –125 124 mV VIN(res) VIN measurement resolution 32.5 mV VIN(rng) VIN voltage measurement range 3.0 20 V VIN(gain) Gain accuracy(13)(14) –2% 2% VIN(gain_adj) Gain adjustment range through PMBus –10% 10% VIN(offst) Offset(13)(14) –5.5 –2 1.4 LSB VIN(offst_adj) Offset adjustment range through PMBus –2 1.968 V THERMAL SHUTDOWN TJSD Junction OT shutdown temperature(14) 135 145 155 °C TJSDH Shutdown hysteresis(14) 25 30 35 °C TJWRN Junction OT warning threshold(14) 120 130 140 °C TJWRNH Junction OT warning temperature hysteresis(14) 15 20 25 °C (9) All read backs are an average of 16 consecutive measurements – not a rolling average. Time is a delay between parameter updates. (10) Constrained by the resolution of READ_IOUT command. This presents as the greater of 122 µV/ IOUT_CAL_GAIN or 62.5 mA, the resolution of the READ_IOUT command (11) Voltage is converted to current by dividing by IOUT_CAL_GAIN, the effective value of the resistance used to sense current in the application. Maximum amount that can be reported via PMBus is 64A. (12) Current reading is only supported to 0 average. Voltage transients to –45mV are taken into account when computing this average. (13) PMBus commands provide for calibration of each device on an individual basis for improved overall system accuracy. (14) Ensured by design. Not production tested.
