TJA1010 is an octal low side driver for relays in automotive applications. It features eight independent low side drivers, small outline/medium power package, serial input control, overvoltage clamping, short-circuit protection, undervoltage shutdown, standby mode for minimum current consumption, etc.
The Philips TJA1010 is an integrated circuit functioning as an Octal Low Side Driver (OLSD). It contains eight independent drivers intended for driving relays in automotive environments, optimized for wide temperature ranges and supply voltage variations. The device utilizes a serial interface to control the outputs via an internal shift register and latch, reducing the number of required microcontroller pins.
