Electrical Characteristics (T

=+ 25°C, Vdd =24V, Note 7)

Symbol Characteristic Test Conditions Min Typ. Max Unit

Vo(sat) Output Saturation Voltage Iout =20mA, B>Bop - 300 500 mV

Ioff Output Leakage Current V

=24V, B<Bop - < 0.1 10 uA

Idd Supply Current Output Open - 4 6 mA

Output Rising Time

=10KΩ, C

=16pF

- 340 - ns

Output Falling Time

=10KΩ, C

=16pF

- 20 - ns

Chopping Frequency - 300 - KHz

Output Current Limit B>Bop (Note 5) 50 70 90 mA

Start-up time of IC Vdd>3V, B>Bop (Note 6) - 47 - us

Notes: 5. The device will shut down operating after the output current I

is over the output current limit I

for 160us (typically). The device will re-start

up operating after resetting the supply voltage Vdd.

6. I

initial power on time, the output state is kept in “High” in this start-up time of IC.

7. Typical data is at T

=+25°C, Vdd=24V and is design information only.

Magnetic Characteristics (T

=+ 25°C, Vdd =3V to 28V, Note 8)

(1mT=10Gauss)

Symbol Parameter Min Typ. Max Unit

Bop Operate Point 5 30 60 Gauss

Brp Release Point -60 -30 -5 Gauss

Bhys Hysteresis - 60 - Gauss

Notes: 8. Magnetic characteristics are for design information, which will vary with supply voltage, operating temperature and after soldering.
