L293WS SMD IC Stepper Motor Driver IC XBLW SOP20 L293D L293WS(XBLW)

Product Overview:

A monolithic integrated high-voltage, high-current four-channel driver designed to accept standard DTL or TTL logic levels. The device is engineered to control inductive loads and switching power transistors, offering separate logic supply controls to permit low-voltage interfacing alongside internal protection safeguards.

Core Specifications:

Manufacturer: XINBOLE (Shenzhen xinbole electronics co., ltd.)

Package Type: DIP-16 (Powerdip) / SOP-20 (Surface Mount)

Function: Push-Pull Four-Channel Driver with Diodes

Input Channels: 4 Independent Driver Channels (arranged in pairs with 2 Enable Inputs)

Control Interface: Standard DTL / TTL Compatible Logic Interface

Features

• High Output Current Capacity: Delivers 600 mA output current capability continuously per individual channel.

• Robust Peak Surge Rating: Supports up to 1.2A non-repetitive peak output current per channel to manage inductive startup spikes.

• Dual Bridge Enable Facility: Channels are equipped with shared enable inputs to easily organize and control dual-bridge configurations.

• Integrated Clamp Diodes: Built-in internal clamp diodes protect control circuitry from inductive voltage kickbacks.

• High Noise Immunity Control: Accommodates a logical low input voltage limit up to 1.5V to handle noisy operating environments.

• Thermal Protection Safeguards: Features overtemperature shutdown protection to preserve the device during fault or heavy-load conditions.

• High Frequency Switching: Well-suited for power switching applications running at clock frequencies up to 5 kHz.

Applications

• DC Motor Controllers: Formulates dual H-bridge configurations for bidirectional DC motor speed and direction management.

• Stepping Motor Drivers: Drives multi-phase bipolar or unipolar stepper motors in industrial automation systems.

• Relay and Solenoid Actuators: Controls high-current relays, contactors, and pneumatic solenoids safely.

• Power Transistor Switching: Acts as a logic-level buffer and high-current pre-driver for power switching networks.
