Texas Instruments ULN2003V12 Low Power 7 channel Relay Driver ULN2003V12PWR

The ULN2003V12PWR is a low-power, 7-channel relay driver from Texas Instruments, designed for driving inductive loads such as relays and motors. It features low output impedance drivers that significantly reduce on-chip power dissipation, allowing it to dissipate up to 12 times less power compared to the ULN2003A when driving a typical 12-V relay coil. The device is compatible with 3.3-V to 5-V CMOS logic inputs, making it suitable for a wide range of microcontrollers and logic interfaces. Each output includes an internal free-wheeling diode for protection against inductive kickback, enhancing reliability in applications. The ULN2003V12 can support up to 1A of load current when multiple channels are paralleled, providing flexibility for higher current applications. It is available in a 16-pin TSSOP package and operates over a temperature range of -40°C to 125°C.
