产品型号ULN2003A的概述

ULN2003A 芯片概述 ULN2003A 是一款广泛使用的多通道功率驱动集成电路，主要用于驱动大功率负载如步进电机、继电器等。其设计的核心是 NPN 达林顿对晶体管的组合，使得芯片能有效承受较大的电流和电压，有效地控制高功率设备，同时具备电气隔离功能。ULN2003A 集成了七个独立的通道，可以同时控制多个设备，减少了外部硬件的数量，从而简化了电路设计。 ULN2003A 详细参数 ULN2003A 的主要参数如下： - 输入电压（VCE）：最大 50V - 集电极电流（IC）：最大 500mA 每通道 - 逻辑电源电压（Vcc）：通常为 5V 至 15V - 输入信号电流（IF）：最小 1.0 mA - 开关速率：最大 1kHz - 功耗：最大 1W（被动散热） - 热阻：约 70°C/W（器件的功耗应加以影响）此外，ULN2003A 采用达林顿结构，使得输入电流和输出电流之间...

HIGH-VOLTAGE, HIGH-CURRENT

DARLINGTON ARRAYS

Ideally suited for interfacing between low-level logic circuitry and

multiple peripheral power loads, the Series ULN20xxA/L high-voltage,

high-current Darlington arrays feature continuous load current ratings

to 500 mA for each of the seven drivers. At an appropriate duty cycle

depending on ambient temperature and number of drivers turned ON

simultaneously, typical power loads totaling over 230 W (350 mA x 7,

95 V) can be controlled. Typical loads include relays, solenoids,

stepping motors, magnetic print hammers, multiplexed LED and

incandescent displays, and heaters. All devices feature open-collector

outputs with integral clamp diodes.

The ULN2003A/L and ULN2023A/L have series input resistors

selected for operation directly with 5 V TTL or CMOS. These devices

will handle numerous interface needs — particularly those beyond the

capabilities of standard logic buffers.

The ULN2004A/L and ULN2024A/L have series input resistors for

operation directly from 6 to 15 V CMOS or PMOS logic outputs.

Dwg. No. A-9594

The ULN2003A/L and ULN2004A/L are the standard Darlington

arrays. The outputs are capable of sinking 500 mA and will withstand

at least 50 V in the OFF state. Outputs may be paralleled for higher

load current capability. The ULN2023A/L and ULN2024A/L will

withstand 95 V in the OFF state.

Note that the ULN20xxA series (dual in-line

package) and ULN20xxL series (small-outline

IC package) are electrically identical and share

a common terminal number assignment.

These Darlington arrays are furnished in 16-pin dual in-line plastic

packages (suffix “A”) and 16-lead surface-mountable SOICs (suffix

“L”). All devices are pinned with outputs opposite inputs to facilitate

ease of circuit board layout. All devices are rated for operation over the

temperature range of -20°C to +85°C. Most (see matrix, next page) are

also available for operation to -40°C; to order, change the prefix from

“ULN” to “ULQ”.
