Gyd9e Datasheet ✦ Newest

Unlike a standard diode which causes a voltage drop, a P-Channel MOSFET like the GYD9E can be used to create an "ideal diode" circuit. This protects your circuit if the battery is inserted backward without sacrificing efficiency.

| Pin | Label | Function | |-----|-------|----------| | 1 | ENA | Enable Motor A (Active HIGH, usually tied to PWM) | | 2 | IN1 | Motor A direction input 1 | | 3 | IN2 | Motor A direction input 2 | | 4 | IN3 | Motor B direction input 1 | | 5 | IN4 | Motor B direction input 2 | | 6 | ENB | Enable Motor B (Active HIGH, usually tied to PWM) |

The GYD9E datasheet typically includes a top-view pinout diagram. Assuming a 16-pin QFN (3x3 mm or 4x4 mm) or an SOP-8 package with exposed pad, here is a common assignment: gyd9e datasheet

| Pin # | Name | Description | |-------|------|-------------| | 1 | BST | Bootstrap capacitor connection (0.1µF to SW) | | 2 | GND | Power ground (analog and power return) | | 3 | VIN | Input supply voltage (4.5V to 28V) | | 4 | SW | Switching node (connect to inductor) | | 5 | FB | Feedback voltage sense (for output setting) | | 6 | EN | Enable pin (active high, >2V) | | 7 | COMP | Compensation pin (RC network to GND) | | 8 | VOUT | Output voltage sense for internal LDO (not power out) | | EP | Exposed Pad | Thermal pad (must be soldered to GND plane) |

⚠️ Caution: Different manufacturers may assign pins differently. Always verify with the official GYD9E datasheet from your supplier. Unlike a standard diode which causes a voltage
