Philips Semiconductors Preliminary specification
Octal Low Side Driver (OLSD) TJA1010
FEATURES
• Eight independent low side drivers
• Small outline/medium power package for surface
mounting, SO28 (20 + 4 + 4)
• Serial input control by writing to internal shift register
• Overvoltage clamping for each driver
• Each driver protected against short-circuited load
• Undervoltage shutdown
• All logic pins CMOS microcontroller compatible
• Standby mode for minimum current consumption
• Two status outputs indicating short-circuited load and
open load respectively at any driver stage
• Channel selective diagnostic information available by
reading from internal shift register
• Serial output allows cascading of several OLSDs
• Outputs can be used in parallel
• Two-stage thermal protection
• Power-on reset.
GENERAL DESCRIPTION
The TJA1010 is an octal low side driver for relays in
automotive applications.
