Description
The L6203 is a full bridge driver for motor control applications realized in Multipower-BCD technology which combines isolated DMOS power transistors with CMOS and Bipolar circuits on the same chip. By using mixed technology it has been possible to optimize the logic circuitry and the power stage to achieve the best possible performance. The DMOS output transistors can operate at supply voltages up to 42V and efficiently at high switching speeds. All the logic inputs are TTL, CMOS and μC compatible.

Introduce this Module:
The L6203 is a DMOS full-bridge driver, which can handle the high peak current up to 5A and supply voltage up to 48V with RDS (ON) of just 0.3 ohms. The chip can run the DC motor at 4 Ampere continuous with proper Heat sinking.
The driver for motor control applications realized in Multipower-BCD technology which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The logic inputs are CMOS, TTL, and μC compatible. Each channel (half-bridge) of the device is controlled by a separate logic input, while a common enable controls two channels. The I.C. is mounted in three different packages.
Some Core Parameters of the Module:
SPECIAL FEATURES :
● THERMAL SHUTDOWN
● CURRENT 5A MAX PEAK
● TTL COMPATIBLE DRIVE
● very HIGH EFFICIENCY
● INTERNAL LOGIC SUPPLY IC
● POWER SUPPLY VOLTAGE UP TO 48V
● TOTAL RMS CURRENT UP TO L620: 4A
● CROSS CONDUCTION PROTECTION CIRCUIT
● OPERATING FREQUENCY UP TO 100 Kilo Hz
● RDS (ON Time) 0.3 ohm (typical value at 25℃)

Pin Connections:
L6203 Pinout Connections:
● Pin 1 - OUT2 (O/P 2) Output of 2nd Half Bridge.
● Pin 2 - Vs (Vcc) Voltages Power Supply.
● Pin 3 - OUT1 (O/P 1) Output of 1st Half Bridge
● Pin 4 - BOOT1 A Boostrap capacitor connected to this pin ensures efficient driving of the upper POWER DMOS transistor. input should remain connected to Power Supply when not used.
● Pin 5 – INPUT1 (IN1) Digital Input from the Motor Controller.
● Pin 6 – GROUND (GND) Common Ground Terminal.
● Pin 7 – INPUT2 (IN2) Digital Input from the Motor Controller.
● Pin 8 – BOOT2 A Boostrap capacitor connected to this pin ensures efficient driving of the upper POWER DMOS transistor. input should remain connected to Power Supply when not used.
● Pin 9 – VREF Internal voltage reference. A capacitor from this pin to Ground is recommended. The internal Ref. Volt can source output a current of 2mA max.
● Pin 10 – SENSE A resistor Rsense connected to this pin provides feedback for motor current control.
● Pin 11 – ENABLE (EN) When a logic high is present on this pin the DMOS POWER transistors are enabled to be selectively driven by IN1 and IN2.

I recently purchased the integrated circuit L6203 from Utsource and I am very pleased with the results. The circuit performed as expected and I was able to test it quickly and easily. The instructions were clear and easy to follow, and the product was well packaged and arrived in perfect condition. I would highly recommend Utsource for anyone looking for a reliable integrated circuit.
