Electrical and Magnetic Parameters
Product characteristics involve the spread of values guaranteed within the specified voltage and temperature
range. Typical characteristics are the median of the production.

1) over operating range, unless otherwise specified. Typical values correspond to V_DD = 12 V and T_A = 25°C
2) To operate the sensor at the max. switching frequency, the magnetic signal amplitude must be 1.4 times higher than for
static fields. This is due to the -3 dB corner frequency of the low pass filter in the signal path.
3) Systematic delay between magnetic threshold reached and output switching
4) Jitter is the unpredictable deviation of the output switching delay
5) B_REP is equivalent to the noise constant
6) Time from applying V_DD ≥ 2.7 V to the sensor until the output state is valid
7) Thermal resistance from junction to ambient
Calculation of the ambient temperature (PG-TSOP6-6-5 example)
e.g. for V_DD = 12.0 V, I_DDtyp = 5.5 mA, V_QSATtyp = 0.3 V and 2 x I_Q = 10 mA :
Power Dissipation: P_DIS = 72.0 mW.
In T_A = T_j – (R_thJA × P_DIS) = 175°C – (100 K / W × 0.072 W)
Resulting max. ambient temperature: T_A = 167.8°C
