PARAMETER TEST CONDITIONS MIN TYP MAX UNIT OFFSET VOLTAGE TA = 25°C 590 608 620 mV Threshold TA = –40°C to 125°C 586 625 mV Hysteresis(1) TA = –40°C to 85°C –8 mV INPUT BIAS CURRENT(2) Input bias current, VMPin PIN 0.005 10 nA Input bias current, VMPin PIN, vs temperature TA = –40°C to 125°C 15 nA INPUT VOLTAGE RANGE Input voltage range, VMPin PIN 0 V to VS – 1.5 V V OUTPUT (OPEN-DRAIN) CMP VOUT 1 V to 4 V, Large-signal differential voltage gain 200 V/mV RL ≥ 15 kΩ Connected to 5 V ILKG High-level leakage current(3)(4) VID = 0.4 V, VOH = VS 0.0001 1 μA VOL Low-level output voltage(3) VID = –0.6 V, IOL = 2.35 mA 220 300 mV RESPONSE TIME RL to 5 V, CL = 15 pF, 100-mV Input Response time(5) 1.3 μs Step with 5-mV Overdrive RESET RESET threshold(6) 1.1 V Logic input impedance 2 M Ω Minimum RESET pulse width 1.5 μs RESET propagation delay 3 μs (1) Hysteresis refers to the threshold (the threshold specification applies to a rising edge of a noninverting input) of a falling edge on the noninverting input of the comparator; refer to Figure 1. (2) Specified by design. (3) VID refers to the differential voltage at the comparator inputs. (4) Open-drain output can be pulled to the range of 2.7 to 18 V, regardless of VS. (5) The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4 V. (6) The RESET input has an internal 2 M Ω (typical) pull-down. Leaving RESET open results in a LOW state, with transparent comparator operation. 6.7 Electrical Characteristics: General At TA = 25°C, VS = 12 V, VCM = 12 V, VSENSE = 100 mV, RL = 10 kΩ to GND, RPULL-UP = 5.1 kΩ connected from CMPOUT to VS, and CMPIN = 1 V, unless otherwise noted. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT POWER SUPPLY VS Operating power supply TA = –40°C to 125°C 2.7 18 V VOUT = 2 V 1350 1800 μA IQ Quiescent current VSENSE = 0 mV, TA = –40°C to 125°C 1850 μA Comparator power-on reset 1.5 V threshold(1) TEMPERATURE Specified temperature –40 125 °C Operating temperature –55 150 °C Storage temperature –65 150 °C VSSOP-8 Surface-Mount 200 °C/W θJA Thermal resistance SOIC-8 150 °C/W (1) The INA200, INA201, and INA202 are designed to power-up with the comparator in a defined reset state as long as RESET is open or grounded. The comparator is in reset as long as the power supply is below the voltage shown here. The comparator assumes a state based on the comparator input above this supply voltage. If RESET is high at power-up, the comparator output comes up high and requires a reset to assume a low state, if appropriate. 6 Submit Documentation Feedback Copyright © 2006–2015, Texas Instruments Incorporated Product Folder Links: INA200 INA201 INA202 |
