Texas Instruments TIOS102/TIOS102x Digital Sensor Output Drivers

Texas Instruments TIOS102/TIOS102x Digital Sensor Output Drivers are configurable as high-side, low-side, or push-pull drivers. These devices can withstand up to 1.2kV (500Ω) of IEC 61000-4-5 surge and feature integrated reverse polarity protection. A pin-programmable interface in the Texas Instruments TIOS102/TIOS102x allows easy interfacing with the circuits. The output current limit can be configured using an external resistor. Fault reporting and internal protection functions are provided for undervoltage, overcurrent, and overtemperature conditions.

Features

Wide supply operation
- 4.75V to 36V supply voltage (TIOS102, TIOS1023)
- 7V to 36V supply voltage (TIOS1025)
PNP, NPN, or push-pull configurable output
Functional safety capable
- Documentation available to aid in functional safety system design
Pin-compatible with TIOS101(x) with improved performance
- Low residual voltage of 0.5V (typical) at 200mA
- Active driver current limiting capability
- Improved thermal performance of the package
- Slower driver slew rates to reduce overshoots (max of 750ns)
Integrated protection features for robust systems
- Configurable driver overcurrent limit (50mA to 350mA)
- Active reverse polarity protection of up to 65V on V_CC, OUT, and GND
- Fault indicator for overcurrent, overtemperature, and UVLO faults
- Safe and fast demagnetization of large inductive loads
- -40°C to 125°C extended ambient temperature operation

Integrated EMC protection on V_CC and OUT
