These devices are designed to drive a wide array of inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current and high-voltage loads. All inputs are TTL compatible and tolerant up to 7 V. Each output is a complete totem-pole drive circuit, with a Darlington transistor sink and a pseudo-Darlington source. Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4 enabled by 3,4EN. When an enable input is high, the associated drivers are enabled, and their outputs are active and in phase with their inputs. When the enable input is low, those drivers are disabled, and their outputs are off and in the high-impedance state. With the proper data inputs, each pair of drivers forms a full-H (or bridge) reversible drive suitable for solenoid or motor applications. On the L293, external high-speed output clamp diodes should be used for inductive transient suppression. On the L293D, these diodes are integrated to reduce system complexity and overall system size. A VCC1 terminal, separate from VCC2, is provided for the logic inputs to minimize device power dissipation. The L293 and L293D are characterized for operation from 0°C to 70°C. 8.2 Functional Block Diagram VCC1 1 0 1 0 1 16 2 15 1 M 14 4 13 5 12 6 11 7 8 M 4 3 2 1 0 1 0 3 10 9 1 0 1 0 M VCC2 Output diodes are internal in L293D. 8.3 Feature Description The L293x has TTL-compatible inputs and high voltage outputs for inductive load driving.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information A typical application for the L293 device is driving a two-phase motor. Below is an example schematic displaying how to properly connect a two-phase motor to the L293 device. Provide a 5-V supply to VCC1 and valid logic input levels to data and enable inputs. VCC2 must be connected to a power supply capable of supplying the needed current and voltage demand for the loads connected to the outputs. 9.2 Typical Application 5V 24 V VCC1 16 10 kΩ VCC2 8 1,2EN 1 1A Control A 1Y 2 3 Motor 2A 2Y 7 6 3,4EN 9 Control B 3A 3Y 10 11 4A 4Y 15 14 Thermal Shutdown 4, 5, 12, 13 GND Figure 6. Two-Phase Motor Driver (L293) 9.2.1 Design Requirements The design techniques in the application above as well as the applications below should fall within the following design requirements. 1. VCC1 should fall within the limits described in the Recommended Operating Conditions. 2. VCC2 should fall within the limits described in the Recommended Operating Conditions. 3. The current per channel should not exceed 1 A for the L293 (600mA for the L293D). 9.2.2 Detailed Design Procedure When designing with the L293 or L293D, careful consideration should be made to ensure the device does not exceed the operating temperature of the device. Proper heatsinking will allow for operation over a larger range of current per channel. Refer to the Power Supply Recommendations as well as the Layout Example.

Bypass capacitors of 0.1 uF or greater should be used at VCC1 and VCC2 pins. There are no power up or power down supply sequence order requirements. Properly heatsinking the L293 when driving high-current is critical to design. The Rthj-amp of the L293 can be reduced by soldering the GND pins to a suitable copper area of the printed circuit board or to an external heat sink. Figure 14 shows the maximum package power PTOT and the θJA as a function of the side of two equal square copper areas having a thickness of 35 μm (see Figure 14). In addition, an external heat sink can be used (see Figure 12). During soldering, the pin temperature must not exceed 260°C, and the soldering time must not exceed 12 seconds. The external heatsink or printed circuit copper area must be connected to electrical ground. 17.0 mm 11.9 mm 38.0 mm Figure 12.
