TPD7000F

The TPD7000F is a kind of power MOS FET driver for low-side switching. This TPD7000F 4-channel driver with a built-in circuit is used to monitor the voltage between the MOSFET drain and source for each channel and to output the state of the power MOSFET. There are some features as follows: (1)low-side N-channel power MOSFET driver (input capacitance: 15 nF max); (2)incorporates a power MOSFET overcurrent protection function; (3)incorporates induction load energy clamping function; (4)INHIBIT option using enable input, open collector output; (5)24-pin SSOP.

The following is about the maximum ratings of TPD7000F (Ta=25): (1)supply voltage, VDH: 25 V when DC and 30 (1s) V when pulse; (2)supply voltage, VDL: 10 V; (3)output voltage, VOPOUT: 10 V; (4)input voltage, VIN: -0.5 to 7 V; (5)output current, IOPOUT: 20 mA; (6)power dissipation, PD: 0.5 W at Ta=25; (7)operating temperature, Topr: -40 to 110; (8)junction temperature, Tj: 150; (9)storage temperature, Tstg: -55 to 150.

The last one is about the electrical characteristics of TPD7000F(Tj=-40 to 110, VDH=13 V, VDL=5±0.5 V): (1)operating voltage, VDH: 8 V min, 13 V typ and 18 V max at VDH pin; (2)operating voltage, VDL: 4.5 V min, 5 V typ and 5.5 V max at VDL pin; (3)current dissipation, IDH: 2 mA typ and 5 mA max at VIN=0 V, VDH=13 V, output off at VDH pin; (4)current dissipation, IDL: 8 mA typ and 12 mA max at VIN=0 V, VDL=5 V, output off at VDL pin; (5)input voltage, VIL: 1.5 V max at pins IN/ENB/OPIN when output off ; (6)input voltage, VIH: 3.5 V min at pins IN/ENB/OPIN when output on; (7)input current, IIL: 1A max at pins IN/ENB/OPIN when VIN=0 V; (8)input current, IIH: 100A typ and 200A max at pins IN/ENB/OPIN when VIN=5 V.
