Product details
Overview
STP16DPS05MTR from STMicroelectronics is a low-voltage 16-bit constant-current LED sink driver with integrated open/short output error detection, serial-in/parallel-out shift register architecture, and adjustable current programming via external resistor (REXT). It delivers 20–100 mA per channel, supports 30 MHz clock frequency, and operates from 3.0–5.5 V supply-enabling high-density LED panel displays in industrial signage and automotive interior lighting.
For engineers reviewing the STP16DPS05MTR datasheet, STP16DPS05MTR pinout, STP16DPS05MTR application, or STP16DPS05MTR equivalent, key selection criteria include its 16-channel sink capability, dual-mode DM1/DM2 detection control, thermal-enhanced TSSOP-24 exposed pad package, and compatibility with 3.3 V microcontrollers for real-time LED fault monitoring.
Technical Context
The STP16DPS05MTR integrates a 16-bit serial-in, parallel-out shift register feeding a 16-bit D-type storage latch, followed by sixteen matched regulated current sinks. Its detection logic uses time-multiplexed operation on LE/DM1 and OE/DM2 pins to identify open, short-to-GND, or short-to-VO faults without additional pins.
Current regulation is set by REXT (970 Ω → 20 mA; 190 Ω → 100 mA), with ±1.5% typical inter-channel accuracy at VDD = 5 V and 25 °C. The device enters auto power-saving mode after 16 clock cycles with no latch update, reducing IDD from 6 mA to 163 μA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output channels | 16 independent constant-current sink outputs for driving LED strings |
| Output current range | 20–100 mA per channel, set precisely via external REXT resistor |
| Current accuracy | ±1.5% typical matching between channels at 5 V, 25 °C |
| Max output voltage | 20 V - enables driving up to 6 white LEDs (3.2 V each) in series per channel |
| Serial clock frequency | 30 MHz - supports high-speed LED refresh rates for flicker-free video-grade displays |
| Error detection modes | Detects open-circuit, short-to-GND, and short-to-VO conditions per output |
| Supply voltage range | 3.0–5.5 V - compatible with both 3.3 V and 5 V logic systems |
Pinout & Package
STP16DPS05MTR is supplied in SO-24 package (not exposed pad), with 24-pin small-outline configuration optimized for surface-mount assembly and moderate thermal dissipation (RthJA = 42.7 °C/W). The exposed pad variant (STP16DPS05XTTR) offers superior thermal performance but is not applicable to this MTR order code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference | Common return path for all output currents and internal logic |
| SDI (Pin 2) | Serial data input | Accepts 16-bit LED on/off data stream synchronized to CLK |
| CLK (Pin 3) | Clock input | Drives shift register; max 30 MHz for full-speed cascade operation |
| LE/DM1 (Pin 4) | Latch enable / Detection Mode 1 | Level-sensitive control: latches data when HIGH; initiates detection sequence with OE/DM2 |
| OUT0–OUT15 (Pins 5–20) | Constant-current sink outputs | Each drives cathode of LED string; 20–100 mA programmable, 20 V tolerant |
| OE/DM2 (Pin 21) | Output enable / Detection Mode 2 | Active-low output control; dual-function pin for entering/resuming detection mode |
| SDO (Pin 22) | Serial data output | Shifts out 16-bit error status or latched data; enables daisy-chaining |
| R-EXT (Pin 23) | Current-setting reference | Connects external resistor to set precise output current across all 16 channels |
| VDD (Pin 24) | Power supply | 3.0–5.5 V input powering logic and output stages; decoupling required |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED sink driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB62786FNG | 16-channel sink driver with 5–100 mA range; lacks integrated open/short detection circuitry | Requires external fault monitoring circuit or MCU GPIO polling for LED health checks | Preferred where cost sensitivity outweighs diagnostic autonomy; same SO-24 footprint |
| IS31FL3728-QFLS4 | I²C interface, 28-channel, PWM dimming; no serial-in/parallel-out architecture or REXT current setting | Designed for RGB matrix control with frame-rate synchronization, not discrete segment driving | Chosen for color-tunable displays needing per-LED grayscale; incompatible pinout and protocol |
Compared with TB62786FNG, STP16DPS05MTR provides autonomous fault detection without firmware overhead; versus IS31FL3728-QFLS4, it offers deterministic timing and simpler 3-wire control ideal for monochrome high-reliability signage.

FAQ
What is the minimum REXT value supported for 100 mA output current?
The datasheet specifies that 100 mA per channel is achieved with REXT = 190 Ω at VDD = 5 V and 25 °C. Using lower resistance values risks exceeding absolute maximum ratings and invalidates current accuracy guarantees. ST does not characterize or recommend operation below 190 Ω.
Can STP16DPS05MTR drive LEDs in common-anode configuration?
No - STP16DPS05MTR is a sink-only driver with 16 N-channel current-regulated outputs. It requires LEDs connected anode-to-VLED and cathode-to-OUTn. Common-anode designs must use source drivers (e.g., STP16DP05) or external high-side switches.
How does the auto power-saving mode affect timing behavior?
After 16 consecutive CLK cycles with no LE/DM1 transition, the device enters shutdown, increasing output rise/fall times by ~2× and adding ~1.05 μs delay between LE assertion and first output response. Full timing performance resumes within one clock cycle upon next LE activation.
Is the SO-24 package of STP16DPS05MTR lead-free and RoHS compliant?
Yes - STP16DPS05MTR is manufactured in ECOPACK®-compliant SO-24 packaging, fully conforming to RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound.
