Product details
Overview
TIOS102YAHR from Texas Instruments is a configurable digital sensor output driver IC with integrated surge and reverse-polarity protection, designed for industrial I/O modules. It supports high-side, low-side, or push-pull operation; delivers 0.5 V typical residual voltage at 200 mA; features ±1.2 kV IEC 61000-4-5 surge immunity on VCC/OUT; and operates across –40°C to 125°C ambient temperature in harsh factory environments.
For engineers reviewing the TIOS102YAHR datasheet, TIOS102YAHR pinout, TIOS102YAHR application, or TIOS102YAHR equivalent, this page provides verified functional configuration options (IN/EN logic control), current-limit tuning via ILIM_ADJ resistor, fault reporting via NFAULT, LDO output selection (3.3 V/5 V), and thermal shutdown behavior - all critical for robust digital output design in PLCs and sensor interfaces.
Technical Context
The TIOS102YAHR implements a dual-mode driver architecture supporting programmable high-side, low-side, or push-pull switching via IN and EN inputs. Its internal LDO (3.3 V or 5 V selectable) powers external logic, while integrated reverse-polarity protection withstands up to ±65 V transients on VCC, OUT, and GND pins.
Current limiting is externally adjustable from 35 mA to 500 mA using an RSET resistor on ILIM_ADJ, with fault detection (overcurrent, overtemperature, UVLO) reported through open-drain NFAULT. Thermal warning triggers at 125°C; shutdown occurs at 150°C with 14°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 4.75 V to 36 V - supports wide industrial 24 V nominal systems with brownout resilience down to 4.4 V UVLO threshold |
| Driver residual voltage | 0.5 V (typical) at 200 mA - enables low-loss switching into inductive loads without excessive power dissipation |
| Surge immunity | ±1.2 kV IEC 61000-4-5 (500 Ω) on VCC/OUT - reduces need for external TVS diodes in DIN-rail mounted equipment |
| LDO output | Selectable 3.3 V or 5 V (via VSEL pin), 20 mA max - powers microcontrollers or sensors directly from 24 V bus |
| Operating temperature | –40°C to +125°C ambient - qualified for under-hood, control cabinet, and motor drive applications |
| Quiescent current | 1.5 mA (typical) when disabled - minimizes standby power in always-on industrial nodes |
| Current limit range | 35 mA to 500 mA (RSET-programmable) - allows precise matching to load requirements and PCB trace limits |
Pinout & Package
TIOS102YAHR uses the 12-pin DSBGA (YAH) package (2.45 mm × 1.7 mm), optimized for space-constrained industrial sensor modules. Thermal performance is enhanced via direct die-to-PCB conduction through the bottom-side solder balls.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, B2 | GND | Primary ground reference for power, logic, and protection circuits; must connect to solid PCB ground plane |
| A2 | OUT | Configurable driver output terminal - sinks or sources current depending on IN/EN state; rated for 500 mA peak |
| A3 | VCC | Main 24 V supply input; accepts 4.75–36 V; powers internal circuitry and LDO; protected against ±65 V reverse transients |
| B1 | ILIM_ADJ | Current limit programming input - connects to GND via resistor (0–110 kΩ) to set output current threshold |
| B3 | VCC_IN / VCC_OUT | Logic supply interface - functions as 3.3 V/5 V LDO output or external logic supply input depending on VSEL state |
| C1 | VSEL | LDO voltage select - floating = 3.3 V output; tied to GND = 5 V output (DSBGA-specific configuration pin) |
| C3 | NFAULT | Open-drain fault indicator - pulled low on overcurrent, overtemperature, or UVLO; requires external pull-up to VCC_IN/OUT |
| D2 | TX / IN | Data input - controls OUT state (low = high-side, high = low-side) when EN is asserted; includes 200 kΩ internal pull-up |
| D3 | EN | Enable input - logic high activates driver; logic low forces OUT into high-impedance state; includes 100 kΩ internal pull-down |
| D1, C2 | NC | No-connect pins - must remain unconnected and floating per datasheet; not internally bonded |
Key Features
| Feature | Design Value |
|---|---|
| Configurable driver topology | High-side, low-side, or push-pull operation selected via IN/EN logic states - eliminates need for external H-bridge or discrete FETs |
| Integrated surge protection | ±1.2 kV IEC 61000-4-5 on VCC/OUT with 100 nF/1 µF decoupling - meets industrial EMC requirements without added components |
| Reverse polarity tolerance | Withstands ±65 V DC between any two pins (VCC/OUT/GND) - prevents damage during field wiring errors in control cabinets |
| Programmable current limit | 35–500 mA range set by single external resistor on ILIM_ADJ - enables precise load matching and avoids overdesign of PCB traces |
| Thermal fault management | 125°C warning flag and 150°C shutdown with 14°C hysteresis - provides early system-level diagnostics before catastrophic failure |
| LDO voltage select | VSEL pin configures 3.3 V or 5 V output in YAH package - supports mixed-voltage sensor subsystems from single 24 V rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital output driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TIOS101YAHR | Lower surge rating (±800 V IEC 61000-4-5); no LDO; fixed 0.7 V residual voltage at 200 mA | Suitable only for less demanding environments without integrated logic supply needs | Choose TIOS101YAHR only if LDO and enhanced surge immunity are unnecessary and cost is primary constraint |
| MAX14914AUB+T | Higher 60 V abs max rating; 400 mA fixed current limit; no VSEL-configurable LDO; SPI interface instead of IN/EN logic | Requires microcontroller firmware support; better suited for centralized diagnostic systems than standalone I/O | Select MAX14914AUB+T when SPI-based configuration and higher voltage margin outweigh need for simple logic-level control |
Compared with TIOS102YAHR, TIOS101YAHR lacks integrated LDO and surge protection, increasing BOM count and reducing system robustness; MAX14914AUB+T adds software complexity and removes analog configurability, trading simplicity for programmability in networked architectures.

FAQ
What is the function of the VSEL pin on TIOS102YAHR?
The VSEL pin on TIOS102YAHR configures the integrated LDO output voltage: connecting it to GND selects 5 V, while leaving it floating selects 3.3 V. This pin is exclusive to the YAH (DSBGA) package and enables single-part flexibility across mixed-voltage sensor subsystems without redesigning the PCB layout for TIOS102YAHR.
How does TIOS102YAHR handle overcurrent conditions?
TIOS102YAHR detects overcurrent via ILIM_ADJ-set threshold and asserts NFAULT low after 200 µs blanking time. The driver disables output but maintains LDO operation. Auto-recovery attempts re-enable the driver every 15 ms until fault clears. Setting ILIM_ADJ to GND disables both indication and recovery, enabling 500 mA peak mode for large capacitive loads.
Can TIOS102YAHR drive inductive loads safely?
Yes - TIOS102YAHR includes active demagnetization circuitry that safely dissipates energy from large inductive loads during turn-off. Combined with ±1.2 kV IEC 61000-4-5 surge immunity on VCC/OUT and reverse-polarity protection up to ±65 V, it ensures reliable operation with solenoids, relays, and valve coils in industrial settings where TIOS102YAHR is deployed.
What is the maximum ambient temperature for continuous operation of TIOS102YAHR?
TIOS102YAHR supports continuous operation from –40°C to +125°C ambient temperature. Its thermal shutdown activates at 150°C junction temperature with 14°C hysteresis, and thermal warning begins at 125°C - allowing system-level monitoring before derating occurs. This makes TIOS102YAHR suitable for sealed control cabinets and motor drive enclosures where TIOS102YAHR operates reliably under thermal stress.
Is TIOS102YAHR pin-compatible with earlier TIOS101 variants?
TIOS102YAHR is not pin-compatible with TIOS101 variants due to the addition of the VSEL pin and reassignment of VCC_IN/VCC_OUT functionality in the YAH package. While both use 12-pin DSBGA footprints, the pin mapping differs - particularly at B3 (dual-function), C1 (VSEL), and D2 (renamed TX). Migration requires PCB layout revision and firmware validation for TIOS102YAHR.
