BLDC / 3-phase inverter
High-side/low-side switch
Half-Bridge Driver based on EG2104
Dual N-Channel MOSFETs in TO252-2 package
Compatible with PWM control logic (IN + SD)
Integrated bootstrap circuit for high-side driving
Gate drive protection diodes for fast switching
Suitable for low-voltage motor control or DC-DC converter designs

Designed for modular assembly of complex topologies (e.g., full-bridge, 3-phase)
| Parameter | Value |
|---|---|
| Input Voltage (VCC) | 0–18 V (12 V recommended) |
| VIN (MOSFET Drain) | 0–18 V |
| PWM Input Voltage | 3.3–5 V (compatible with logic level) |
| Enable Pin (SD) | HIGH to enable (3.3 V–5 V) |
| Output Current | Up to MOSFET rating (typically 5–10 A depending on heatsinking) |
| Switching Frequency | Up to 100 kHz (EG2104 limit) |
Note: VIN and VCC can be same or isolated based on application.
| Pin | Name | Description |
|---|---|---|
| 1 | GND | Power Ground |
| 2 | VCC | Driver Supply Voltage (logic) |
| 3 | VIN | Power to MOSFET drain (motor/DC) |
| 4 | SW | Switch Output (between MOSFETs) |
| 5 | IN | PWM signal input (logic level) |
| 6 | SD | Enable pin (high to activate) |
Board Size: ~28 mm × 25 mm
Mounting: 2.54mm pin headers for breadboard or sockets
Silkscreen Labeling: Clearly marked pins and orientation
SMD Components: Professionally assembled with compact layout
MOSFET Heatsinking: TO252 pads with thermal vias for heat dissipation
Ensure proper heatsinking and ventilation at high currents.
Bootstrap capacitor is included for high-side drive.
SD pin must be HIGH for operation (defaults to NC, add pull-up as needed).
The circuit has onboard fast Schottky diodes for improved switching speed.
| IN | SD | HO (High-Side Gate) | LO (Low-Side Gate) |
|---|---|---|---|
| 0 | 1 | OFF | ON |
| 1 | 1 | ON | OFF |
| X | 0 | OFF | OFF |
Note: SD = 0 disables both outputs regardless of IN.
