TD-075

TD Over Current Detector Description Hall effect type current sensor with a single digital output factory programmed to go low when a given current threshold is exceeded. The TD Series is able to operate within a temperature range of -40o C to 125o C and has a fast response time of 1!s (typical). The miniature package size allows the TD series to be mounted on printed circuit boards and is integrated with an open collector digital output which is ideal for interfacing to control circuitry. Typical Applications Welding equipment, servo drives, treadmills, automotive power conversion, power supplies, home audio, MRI equipment Series TD Ordering Information Technical Data Type No TD Over Current Detector Trip Point 015 15 Amp 020 20 Amp 025 25 Amp 030 30 Amp 035 35 Amp 040 40 Amp 045 45 Amp 050 50 Amp 055 55 Amp 060 60 Amp 065 65 Amp 070 70 Amp 075 75 Amp 080 80 Amp 085 85 Amp 090 90 Amp 095 95 Amp 100 100 Amp 105 105 Amp 110 110 Amp 115 115 Amp 120 120 Amp 125 125 Amp TD 025 = ordering example Absolute Maximum Ratings Supply Voltage Voltage Externally Applied to Output Output ON current (sink) Operating Temp Range Sensed Current RMS voltage for AC isolation test, 50/60 Hz, 1 minute -1.0 to +25 VDC +25 VDC max (Output high, current below Itrip) -0.5 VDC min (Output high or low) 50 mA -40o C to +125o C +/- 500 Amp peak 2.5 kVac Absolute maximum ratings are the extreme limits that the detector will withstand without damage. Electrical operation and characteristics are not guaranteed as the maximum limits are approached. Proper application of the detector must ensure that the detector operates within the operating characteristics below.
