TIOS102 and TIOS102x Digital Sensor Output Drivers with Integrated Surge

Protection In Small Packages

1 Features

• Wide supply operation

– 4.75-V to 36-V supply Voltage (TIOS102,

TIOS1023)

– 7-V to 36-V 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 0.5 V (typical) at 200

mA

– Active driver current limiting capability

– Improved thermal performance of the package

– Slower driver slew rates to reduce overshoots

(max of 750 ns)

• Integrated protection features for robust systems

– Configurable driver overcurrent limit (50 mA to

350 mA)

– Active reverse polarity protection of up to 65 V

on VCC, OUT and GND

– Fault indicator for overcurrent, overtemperature

and UVLO faults

– Safe and fast demagnetization of large

inductive loads

– Extended ambient temperature operation:

-40°C to 125°C

• Integrated EMC protection on VCC and OUT

– ±8 kV IEC 61000-4-2 ESD contact discharge

– ±4 kV IEC 61000-4-4 Electrical fast transient

– ±1.2 kV/500 Ω IEC 61000-4-5 Surge

• Large capacitive load driving capability

• < 1.5-mA (typical) quiescent supply current (when

driver is disabled)

• Integrated LDO options for up to 20 mA current

– TIOS1023: 3.3-V LDO

– TIOS1025: 5-V LDO

– TIOS1023L (DSBGA): Selectable 3.3-V/5-V

LDO output

• Small space-saving package options

– 3 mm x 3 mm 10-pin VSON package (pin-

compatible with TIOS101)

– 1.7 mm x 2.45 mm DSBGA package

2 Applications

• Proximity Switches

• Capacitive and Inductive Sensors

• Actuators

• Digital Outputs

3 Description

The TIOS102(x) devices are configurable as high-

side, low-side or push-pull drivers. These devices

are capable of withstanding up to 1.2 kV (500 Ω) of

IEC 61000-4-5 surge and feature integrated reverse

polarity protection.

A pin-programmable interface allows easy interfacing

to 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.
