11 / 17 page Data Sheet 9 V 2.0, 2009-01 TLE4906K TLE4906L Specification 3.3 Electrical and Magnetic Characteristics Table 6 General Electrical Characteristics1) 1) over operating range, unless otherwise specified. Typical values correspond to VS = 12V and TA = 25°C Parameter Symbol Values Unit Note / Test Condition Min. Typ. Max. Supply current IS 2 4 6 mA VS = 2.7V ... 18V Reverse current ISR 0 0.2 1 mA VS = -18V Output saturation voltage VQSAT - 0.3 0.6 V IQ = 20mA Output leakage current IQLEAK - 0.05 10 µA for VQ = 18V Output fall time tf - 0.02 1 µs RL = 1.2kΩ; CL = 50pF see Figure 3 Output rise time tr - 0.4 1 µs Chopper frequency fOSC - 320 - kHz Switching frequency fSW 0 - 2) To operate the sensor at the max. switching frequency, the value of the magnetic signal amplitude must be 1.4 times higher than for static fields. This is due to the -3dB corner frequency of the low pass filter in the signal path. 152) kHz Delay time 3) Systematic delay between magnetic threshold reached and output switching. 3) td - 13 - µs Output jitter 4) Jitter is the unpredictable deviation of the output switching delay. 4) tQJ - 1 - µsRMS typical value for square wave signal with 1kHz Power-on time 5) Time from applying VS ≥ 2.7V to the sensor until the output state is valid. 5) tPON - 13 - µs VS ≥ 2.7V Thermal resistance 6) Thermal resistance from junction to ambient. 6) RthJA - 100 - K/W SC59 - - 190 PG-SSO-3-2 Product characteristics involve the spread of values guaranteed within the specified voltage and ambient temperature range. Typical characteristics are the median of the production. Calculation of the ambient temperature (SC59 example) e.g. for VS = 12.0V, IStyp = 4mA, VQSATtyp = 0.3V and IQ = 20mA Power dissipation PDIS = 54.0mW In TA = Tj - (RthJA x PDIS) = 175°C - (100K/W x 0.054W) Resulting max. ambient temperature: TA = 169.6°C |
