Description
The Device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.
To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included.
This device is suitable for use in switching applications at frequencies up to 5 kHz.
The L293D is assembled in a 16 lead plastic packaage which has 4 center pins connected together and used for heatsinking
The L293DD is assembled in a 20 lead surface mount which has 8 center pins connected together and used for heatsinking
Key Features
- 600mA OUTPUT CURRENT CAPABILITY PER CHANNEL
- 1.2A PEAK OUTPUT CURRENT (non repetitive) PER CHANNEL
- ENABLE FACILITY
- OVERTEMPERATURE PROTECTION
- LOGICAL "0" INPUT VOLTAGE UP TO 1.5 V (HIGH NOISE IMMUNITY)
- INTERNAL CLAMP DIODES
L293D是专用驱动集成电路，属于H桥集成电路，其输出电流为600mA，电流1.2A，工作电压36V，可以驱动感性负载，比如：小型直流电机，继电器、步进电机和开关电源晶体管，特别是其输入端可以与单片机直接相联，从而很方便地受单片机控制。当驱动小型直流电机时，可以直接控制两路电机，并可以实现电机正转与反转，实现此功能只需改变输入端的逻辑电平。

Standard Grade Typical Temperature Drift (TL431B) 6 mV (C Temp) 14 mV (I Temp, Q Temp) Low Output Noise 0.2-Ω Typical Output Impedance Sink-Current Capability . . . 1 mA to 100 mA Adjustable Output Voltage . . . Vref to 36 V 说明 The TL431 and TL432 are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors (see Figure 17). These devices have a typical output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power su...
