Product details
Overview
STP16DPP05MTR from STMicroelectronics is a 16-bit constant-current LED sink driver IC designed for LED panel displays and signage systems. It delivers precise 3–40 mA per channel via external R-EXT resistor, supports open/short LED error detection without extra pins, and operates from 3 V to 5.5 V supply with 30 MHz serial clock capability.
For engineers reviewing the STP16DPP05MTR datasheet, STP16DPP05MTR pinout, STP16DPP05MTR application, or STP16DPP05MTR equivalent, key selection criteria include output current accuracy (±1% between bits), thermal performance in SO-24 package (RthJA = 42.7 °C/W), error detection logic sequencing, and 3.3 V MCU interface compatibility.
Technical Context
The device integrates a 16-bit serial-in/parallel-out shift register feeding a D-type storage register, followed by sixteen matched current-regulated sinks. Output current is set by an external resistor connected to R-EXT, enabling precise brightness control across all 16 channels.
Error detection operates in three phases-entry, analysis, and exit-using dedicated timing sequences on OE/DM2 and LE/DM1 pins. Detection identifies open-circuit, short-to-GND, and short-to-VO conditions by monitoring output voltage and current thresholds during a controlled test cycle.
Key Specifications

|---|---|
| Output channels | 16 independent constant-current sinks for LED anode connection |
| Output current range | 3–40 mA per channel, adjustable via external R-EXT resistor |
| Current accuracy | ±1% between outputs at 5 mA, ±0.5% at 40 mA (ensures uniform LED brightness) |

Pinout & Package
STP16DPP05MTR is supplied in SO-24 package (24-pin small outline) with gull-wing leads and standard JEDEC footprint. The exposed pad variant is not used in this order code; thermal resistance is 42.7 °C/W (junction-to-ambient).

| 1 GND | Ground reference | Primary return path for all 16 output currents and internal logic |
| 2 SDI | Serial data input | Accepts 16-bit LED on/off data stream synchronized to CLK |
| 3 CLK | Clock input | Drives shift register; 30 MHz max enables rapid data loading |
| 4 LE/DM1 | Latch enable / detect mode 1 | Level-sensitive control: high loads data into output register; low holds previous state; part of 5-cycle entry/exit sequence for error detection |
| 5–20 OUT0–OUT15 | Constant-current sink outputs | Each drives LED cathodes with programmable 3–40 mA; supports 20 V compliance |
| 21 OE/DM2 | Output enable / detect mode 2 | Active-low output control; also initiates error detection when toggled in sequence with LE/DM1 |
| 22 SDO | Serial data output | Shifts out 16-bit error status or normal data; enables daisy-chaining |
| 23 R-EXT | Current programming input | Connects external resistor to set all 16 output currents simultaneously |
| 24 VDD | Power supply | 3.0–5.5 V operation; powers logic and current sources |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED sink driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC59283RTJR | 16-bit sink driver with 3–120 mA range; no integrated open/short detection; requires external I2C interface | Lacks autonomous error detection; suited for simpler LED arrays where diagnostics are handled externally | Choose when higher current headroom (120 mA) is needed and system-level fault checking is already implemented |
| MAX7219CWG+ | 8-bit driver with SPI interface; includes scan-limiting, intensity control, and shutdown; no per-output current programming | Designed for 7-segment/matrix displays-not optimized for high-current LED panels or individual channel calibration | Prefer for alphanumeric displays or low-power indicator banks where integrated decoding and multiplexing add value |
Compared with TLC59283RTJR and MAX7219CWG+, the STP16DPP05MTR uniquely combines per-channel current adjustability, integrated open/short detection, and 30 MHz serial throughput in a single SO-24 package-making it optimal for high-reliability LED panel systems requiring both precision and self-diagnostics.

FAQ
What is the maximum number of STP16DPP05MTR devices that can be daisy-chained?
Up to 16 devices can be daisy-chained using SDI/SDO lines without signal degradation, provided PCB trace lengths are kept under 10 cm per segment and termination resistors (100 Ω) are placed at the final SDO node. The 30 MHz clock supports full 256-bit (16 × 16) refresh within 8.5 µs.
How does the R-EXT resistor value map to output current?
R-EXT sets current per channel using IOUT ≈ 12.5 V / REXT. For example, 497 Ω yields ~25.1 mA; 1 kΩ yields ~12.5 mA. Table 11 in the datasheet provides exact values from 1 mA (23.7 kΩ) to 60 mA (331 Ω), measured at 25 °C with VDD = 3.3 V or 5.0 V.
Can STP16DPP05MTR drive LEDs with forward voltages above 3.3 V?
Yes-the device supports up to 20 V output compliance, enabling series strings of up to six 3.3 V white LEDs (19.8 V total). Dropout voltage remains below 726 mV at 40 mA (VDD = 5.0 V), ensuring stable regulation even with higher VF stacks.
Is the SO-24 package of STP16DPP05MTR RoHS-compliant and lead-free?
Yes-STP16DPP05MTR is manufactured in ST's ECOPACK®2-compliant SO-24 package, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. Lead finish is matte tin (Sn), with peak reflow temperature rated to 260 °C per JEDEC J-STD-020.
