Product details
Overview
STP16DP05MTR 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 output current (5–100 mA) via external resistor REXT. It operates from 3.0 V to 5.5 V, supports 30 MHz clock frequency, and delivers 20 V output driving capability for multi-LED series strings in signage and panel displays.
For engineers reviewing the STP16DP05MTR datasheet, STP16DP05MTR pinout, STP16DP05MTR application, or STP16DP05MTR equivalent, key selection criteria include its 16-channel sink current regulation accuracy (±1.5% between bits), thermal-enhanced TSSOP-24 exposed pad package, dual-mode pin functionality (LE/DM1 and OE/DM2 for latch/detection control), and compatibility with 3.3 V microcontrollers.
Technical Context
The STP16DP05MTR integrates a 16-bit serial-in, parallel-out shift register feeding a 16-bit D-type storage register, followed by sixteen matched regulated current sinks. Its detection mode uses dedicated logic sequencing on LE/DM1 and OE/DM2 pins-without added pins-to identify open-circuit, short-to-GND, or short-to-VO faults per channel.
Output current is set by an external REXT resistor (e.g., 970 Ω → 20 mA; 190 Ω → 100 mA), with ±1.5% typical inter-channel accuracy at 25 °C. The device supports cascaded operation with propagation delays as low as 20 ns (VDD = 5 V) and includes thermal shutdown at ~170 °C, disabling outputs only while preserving logic functionality.

Key Features
| Feature | Design Value |
|---|---|
| 16-bit constant-current sink | Enables uniform brightness across 16 independent LED strings without external current-setting resistors per channel |
| Integrated open/short detection | Reduces system-level fault diagnostics to one serial read - no additional sense circuitry or ADC required |

| 30 MHz serial interface | Supports >480 kSPS update rates for 16-bit frames - sufficient for real-time video-rate LED matrix refresh |
| 20 V output compliance | Allows direct drive of longer LED strings (e.g., 6× white LEDs @ 3.2 V) without boost converters or external transistors |
Applications
| Indoor LED Signage | Industrial Panel Displays |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit constant-current LED sink driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC59283RGER | Higher max current (120 mA), but no integrated open/short detection; requires external fault monitoring circuitry | Suitable for cost-sensitive lighting where diagnostics are handled at MCU level | Choose when higher current headroom is needed and diagnostic overhead can be absorbed by host processor |
| MAX6967AUG+T | Includes I²C interface and built-in PWM dimming registers; lacks 30 MHz serial clock support and 20 V compliance | Better for compact, low-pin-count designs with I²C master availability | Prefer when system already uses I²C infrastructure and lower output voltage (≤12 V) suffices |
Compared with TLC59283RGER and MAX6967AUG+T, the STP16DP05MTR uniquely combines high-speed serial control, 20 V output compliance, and pin-efficient fault detection - making it optimal for industrial signage and HMI panels where reliability, voltage margin, and diagnostic integration are critical.

FAQ
What is the minimum supply voltage required for reliable operation of STP16DP05MTR?
The STP16DP05MTR operates reliably down to 3.0 V, as specified in its recommended operating conditions (Table 6). At this voltage, it maintains full functionality including 20 mA output current capability (with REXT = 970 Ω), 30 MHz clock tolerance, and open/short detection - verified across −40 to +125 °C ambient temperature range.
How does the STP16DP05MTR implement open/short detection without adding pins?
It uses a three-phase logic sequence applied to OE/DM2 and LE/DM1 pins over five clock cycles to enter detection mode. During phase two, all outputs are driven ON; then OE/DM2 is pulsed low to activate detection circuitry that measures current and voltage per channel. Results shift out via SDO - no extra pins or external components required.
Can STP16DP05MTR drive LEDs in series, and what is the maximum string length?
Yes - each output supports up to 20 V compliance. With typical white LEDs at 3.2 V forward voltage, this allows up to six LEDs in series per channel (6 × 3.2 V = 19.2 V). At 5 V supply, dropout voltage remains sufficient for full current regulation across the full 5–100 mA range.
Is STP16DP05MTR pin-compatible with STP16C596 or STP16L596?
Yes - ST confirms backward compatibility with STP16C/L596 in the datasheet (Section 1). Pinout, function mapping, and electrical behavior (including detection mode entry sequence) are identical. However, STP16DP05 offers improved current accuracy (±1.5% vs. ±3%) and enhanced ESD protection (2.5 kV HBM).
