Product details
Overview
TIOS1023LYAHR from Texas Instruments is a configurable digital sensor output driver with integrated surge and reverse-polarity protection, designed for industrial I/O modules. It supports high-side, low-side, or push-pull operation; delivers 3.3-V LDO output up to 20 mA; features ±1.2 kV IEC 61000-4-5 surge immunity on VCC/OUT; and operates across –40°C to 125°C ambient temperature.
For engineers reviewing the TIOS1023LYAHR datasheet, TIOS1023LYAHR pinout, TIOS1023LYAHR application, or TIOS1023LYAHR equivalent, this page provides verified functional safety–capable driver specifications, DSBGA package layout details, current-limit configuration guidance, and validated alternatives for proximity switch and inductive sensor interface designs.
Technical Context
The TIOS1023LYAHR implements a configurable driver core with programmable output current limit (50–350 mA via external RSET), active reverse polarity protection up to ±65 V on VCC, OUT, and GND, and integrated diagnostics including overcurrent, overtemperature (TSDN = 150°C), and UVLO fault reporting via open-drain NFAULT. Its 3.3-V LDO regulator supplies local logic with <1.5 mA quiescent current when disabled.
It uses a 12-pin DSBGA (YAH) package with thermal pad, enabling compact placement in space-constrained industrial sensors. Pin VSEL selects LDO output voltage (3.3 V floating, 5 V grounded), while ILIM_ADJ enables precise current-limit tuning - critical for driving capacitive loads and demagnetizing inductive actuators without overshoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.75 V to 36 V - powers directly from 24-V industrial rails with UVLO at 4.4 V (falling) and 4.75 V (rising) |
| LDO Output | 3.3 V ±3.5% @ 20 mA - stable with ≥1 µF ceramic capacitor; drop-out voltage ≤1.4 V |
| Driver Residual Voltage | 0.5 V (typical) at 200 mA - ensures low power loss and minimal heating during sustained load drive |
| Surge Immunity | ±1.2 kV IEC 61000-4-5 (500 Ω) on VCC/OUT - eliminates need for external TVS diodes in standard industrial environments |
| ESD Protection | ±8 kV IEC 61000-4-2 contact discharge on VCC/OUT/GND - meets EN 61000-6-2 immunity requirements |
| Operating Temperature | –40°C to +125°C ambient - qualified for under-hood and factory-floor deployment without derating |
| Current Limit Range | 50 mA to 350 mA via RSET (0–110 kΩ) - enables safe driving of diverse sensor/actuator loads |
Pinout & Package
TIOS1023LYAHR is housed in a 2.45 mm × 1.7 mm, 12-pin DSBGA (YAH) package with exposed thermal pad connected to GND for optimal thermal dissipation (RθJB = 19.5°C/W). The package is compatible with standard SMT reflow profiles and supports automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, B2 | GND | Primary ground reference for analog/digital sections and thermal pad connection point |
| A2 | OUT | Configurable driver output - sinks or sources current based on IN/EN logic states |
| A3 | VCC | Main 4.75–36 V supply input - powers internal circuitry and LDO; withstands ±65 V reverse transients |
| B1 | ILIM_ADJ | Analog input for external RSET - sets output current limit from 50 mA to 350 mA |
| B3 | VCC_OUT | 3.3-V regulated output - powers microcontroller I/O or sensor front-end; max 20 mA load |
| C1 | VSEL | LDO voltage select - floating = 3.3 V; grounded = 5 V (only in YAH package variants) |
| C3 | NFAULT | Open-drain fault indicator - asserts low for overcurrent, overtemperature, or UVLO conditions |
| D2 | TX (IN) | Logic input controlling OUT state - weak internal pull-up; high = low-side drive, low = high-side drive |
| D3 | EN | Enable input - logic low places OUT in Hi-Z; weak internal pull-down |
Key Features
| Feature | Design Value |
|---|---|
| Configurable output topology | Supports high-side, low-side, or push-pull drive via EN/IN logic - eliminates need for external transistor arrays |
| Integrated 3.3-V LDO | Delivers up to 20 mA with <1.5 mA quiescent current when disabled - powers MCU peripherals without secondary regulator |
| Programmable current limiting | Adjustable 50–350 mA limit using single external resistor - prevents latch-up during inductive load switching |
| Robust transient protection | ±1.2 kV IEC 61000-4-5 surge + ±65 V reverse polarity tolerance on VCC/OUT/GND - reduces BOM count by 3+ discrete protectors |
| Diagnostic fault reporting | NFAULT pin signals overcurrent, overtemperature (125°C warning / 150°C shutdown), and UVLO - enables predictive maintenance in PLC systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital output driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TIOS1023DR | VSON-10 package (3 mm × 3 mm); no VSEL pin; fixed 3.3-V LDO | Requires larger PCB footprint; lacks LDO voltage select flexibility | Choose for legacy board reuse where DSBGA assembly is unavailable |
| MAX14914AUB+ | 4.5–36-V supply; 5-V LDO only; ±1 kV surge; no VSEL; different pinout | Higher quiescent current (2.5 mA); no 3.3-V LDO option; requires external current-sense resistor | Choose when 5-V-only logic supply is mandated and thermal performance margin is >10°C |
Compared with TIOS1023LYAHR, TIOS1023DR trades package miniaturization for assembly compatibility, while MAX14914AUB+ sacrifices LDO flexibility and surge margin for broader vendor support - making TIOS1023LYAHR optimal for new space-constrained, dual-voltage industrial designs.

FAQ
What is the LDO output voltage configuration for TIOS1023LYAHR?
The TIOS1023LYAHR features a pin-selectable LDO: when VSEL (pin C1) is left floating, VCC_OUT delivers 3.3 V; when VSEL is tied to GND, it delivers 5 V. This dual-voltage capability allows one BOM to serve both 3.3-V and 5-V microcontroller interfaces without redesign. The LDO remains active even during driver faults, ensuring continuous logic power.
How does TIOS1023LYAHR handle inductive load demagnetization?
TIOS1023LYAHR integrates active demagnetization circuitry that safely dissipates stored energy in inductive loads (e.g., solenoids, relays) during turn-off. Unlike passive snubbers, this feature reduces de-energization time by up to 40% and eliminates external components. It operates automatically in all output configurations - high-side, low-side, or push-pull - without software intervention.
Can TIOS1023LYAHR be used in high-EMI factory environments?
Yes. TIOS1023LYAHR meets IEC 61000-4-4 (±4 kV EFT) and IEC 61000-4-5 (±1.2 kV surge) standards on VCC and OUT pins, and includes ±8 kV IEC 61000-4-2 ESD protection. Its integrated reverse polarity protection (±65 V) and fault-indicating NFAULT pin enable reliable operation in noisy 24-V industrial bus environments without additional filtering or clamping circuits.
What is the maximum continuous output current for TIOS1023LYAHR?
The TIOS1023LYAHR supports a programmable continuous output current limit from 50 mA to 350 mA, set by an external resistor on ILIM_ADJ. At 200 mA, its typical residual voltage is 0.5 V, yielding <100 mW conduction loss. Thermal derating begins above 100°C ambient, with automatic shutdown at 150°C junction temperature to prevent damage.
Is TIOS1023LYAHR pin-compatible with earlier TIOS101-series devices?
No. While TIOS1023LYAHR shares functional equivalence with TIOS101(x) drivers, it uses a 12-pin DSBGA (YAH) package - incompatible with the 10-pin VSON or older DSBGA footprints. However, its pin functions (e.g., IN, EN, NFAULT, VCC_OUT) align logically with TIOS101x, simplifying firmware migration. Board redesign is required for mechanical replacement.
