Features

• Wide operating supply voltage range (3.6 V to 34 V) (The voltage is limited within a range between 3.6 V and 17 V if it is connected to a step-down volt1.27 (0.605) 0.40±0.25 age circuit.) Seating plane
• Totem pole output circuit: output peak current (±1 A) SOP016-P-0225A
• On-chip pulse-by-pulse overcurrent detection and protection circuit Threshold voltage VCC − 0.095 V typical
• On-chip bootstrap circuit (allowing n-channel MOSFET direct driving.)
• On-chip under-voltage lock-out circuit (U.V.L.O.)
• On-chip on/off function (active-high control input, standby current of maximum 5 µA)
