... BD2202G,BD2206G ● Operation description BD2202G and BD2206G are high side switch IC with over-current protection function. The operating voltage range is from 2.7V to 3.6V and the current limit value is set on 400mA, 1A. When an over-current condition lasts longer than an over-current shutdown time, the switch turns OFF. The OFF switch is set on latch mode ...

... BD2202G,BD2206G ● Application information When an excessive current flows because of an output short circuit, a noise caused by the inductance of power supply to the IC breaks out and it is possible that it influences negatively the IC operation. In order to avoid this problem, please connect C bypass capacitor close to the IC VIN and GND pins of the IC. More than 1µF is recommended. ...

... BD2202G,BD2206G (4) Power supply line Design PCB pattern to provide low impedance for the wiring between the power supply and the GND lines. In this regard, for the digital block power supply and the analog block power supply, even though these power supplies has the same level of potential, separate the power supply pattern for the digital block from that for the analog block, thus suppressing the diffraction of digital noises to the analog block power supply resulting from impedance common to the wiring patterns ...
