L293D

HTC Korea L293D device is quadruple high-current half-H driver. The L293D is  designed to provide bidirectional drive currents of up to 600mA at voltages from 4.5V to 36V. The device is designed to driver inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications. 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 EN1/2 and drivers 3 and 4 enabled by EN3/4. The L293D is characterized for operation from 0°C to 70°C.

L293D features :

• Wide supply-voltage range: 4.5V to 36V
• Separate input-logic supply
• Internal ESD protection (HBM 2kV)
• High-noise-immunity inputs
• Output current 600mA per channel
• Peak output current 1.2A per channel
• Output clamp diodes for inductive transient suppression

L293D applications :

• Stepper motor drivers
• DC motor drivers
• Latching relay drivers
