What are the key features of TPL9201PWP?
- 8 independent relay driver channels at up to 150 mA per channel from a single 16.5 V supply
- Integrated 5 V LDO regulator powers logic circuitry directly from the relay supply rail without an external regulator
- Zero-volt detection monitors relay coil switching for diagnostics and safe relay de-energization in industrial control systems
What is TPL9201PWP used for?
The TPL9201PWP is designed for PLC output modules, relay boards, and industrial process control panels requiring multi-channel relay switching with minimal external components. Its integrated 5 V LDO reduces BOM by eliminating a separate logic supply regulator, while the 8 channels cover a full octet of relay outputs in a single 20-pin IC. The zero-volt detection feature enables safe switching diagnostics in HVAC controllers, building automation, and industrial IO interfaces operating from 12 V to 16.5 V supply rails.

Frequently Asked Questions
How many relay coils can TPL9201PWP drive simultaneously and what is the per-channel current limit?
TPL9201PWP drives up to 8 relay coils simultaneously, each channel sinking up to 150 mA from supply voltages up to 16.5 V. This is sufficient to energize standard 5 V or 12 V relay coils with coil currents between 30 mA and 120 mA, covering the majority of general-purpose relay types used in PLC output cards and industrial IO boards.
What does the integrated 5 V LDO in TPL9201PWP provide and how does it simplify relay board power design?
The onboard 5 V LDO in TPL9201PWP supplies logic-level power from the same rail used for relay coils, eliminating a separate 5 V regulator IC. In a typical 12 V relay board, this saves one regulator component and its associated decoupling capacitors, reducing BOM by at least 3 parts and simplifying the power distribution layout to a single supply input.
For an 8-output PLC module running from a 12 V DIN rail supply, how does TPL9201PWP compare to discrete driver arrays like ULN2803?
TPL9201PWP integrates an 8-channel driver, 5 V LDO, and zero-volt detection in a 20-pin TSSOP, whereas ULN2803 provides only 8 Darlington driver channels in an 18-pin package without any power management. For 12 V PLC modules, TPL9201PWP reduces the board footprint by eliminating a separate LDO regulator and adds coil switching diagnostics not available in ULN2803, at the cost of a slightly larger 20-pin body versus ULN2803's 18 pins.
What does zero-volt detection mean in TPL9201PWP and why is it important for relay switching in AC load control?
Zero-volt detection in TPL9201PWP monitors the relay coil drive signal for near-zero voltage conditions, enabling the IC to detect whether a relay failed to energize or has de-energized unexpectedly. In AC load switching applications, this diagnostic reduces relay contact arcing by confirming the coil state before switching, extending relay contact life in 250 V AC circuits where multiple make-break cycles per minute occur in HVAC and building automation systems.
