DBx (D5) は Current DET Enable 時のみ有効となります。
Load dump voltage detection enable (D7 = 1) Diseble (D6 = 0)
Rare short detection enable (D6 = 1) Diseble (D6 = 0)
Channel 4 current detection
Output peak current < 250 mA (IB2 − D7 = 0) − open load (D5 = 1)
Output peak current < 100 mA (IB2 − D7 = 1) − open load (D5 = 1)
Output peak current > 500 mA (IB2 − D7 = 0) − normal load (D5 = 0)
Output peak current > 300 mA (IB2 − D7 = 1) − normal load (D5 = 0)
