The **HIP2103-4DEMO2Z** is a demonstration board designed to evaluate the **HIP2103** and **HIP2104**, which are high-frequency 60V Half-Bridge MOSFET drivers. This board is specifically tailored for small form-factor applications like power tools, drones, and DC/DC converters. --- ## 1. Core Electronic Components The board is composed of several critical subsystems. Below is a breakdown of the primary electronic parts: | Component Type | Part Number / Detail | Function | | :--- | :--- | :--- | | **Bridge Driver IC** | HIP2103 / HIP2104 | A half-bridge driver that controls the High-Side and Low-Side MOSFETs. | | **Power MOSFETs** | N-Channel MOSFETs | Typically 40V-60V rated, these perform the actual switching of the load. | | **LDO Regulator** | Integrated (HIP2104) | Provides a 3.3V or 5V rail to power external microcontrollers. | | **Bootstrap Diode** | Integrated | Charges the high-side gate drive capacitor without external parts. | | **Decoupling Caps** | Multilayer Ceramic (MLCC) | Filters noise and provides instantaneous current for gate switching. | --- ## 2. Key Technical Features ### A. The Driver Architecture The HIP2103/4 ICs are the "brains" of the board. They translate low-power logic signals (from a MCU) into high-current pulses to charge and discharge the gates of the MOSFETs. * **Operating Voltage:** Up to 60VDC. * **Integrated Bootstrap:** Eliminates the need for an external discrete diode, saving PCB space. ### B. On-board Voltage Regulation The **HIP2104** variant included on the demo board features an integrated Linear Regulator (LDO). * **Input:** VCC (up to 14V). * **Output:** Typically 3.3V at 10mA. * **Purpose:** Powers a small microcontroller or logic circuit directly from the driver supply. --- ## 3. Pinout and Interface Summary The demo board provides header pins for easy interfacing with an oscilloscope or a signal generator. ```cpp // Logic Input Mapping Example HI_IN -> // High-side control (PWM) LI_IN -> // Low-side control (PWM) VDD -> // Logic Supply (3.3V - 5V) VSS -> // Ground VCC -> // Driver Supply (8V - 14V) ``` --- ## 4.
