Product details

Overview

STP16CPC05MTR from STMicroelectronics is a 16-channel constant-current LED sink driver IC with serial-in/parallel-out shift register architecture, designed for LED panel displays. It delivers adjustable output current (5–100 mA per channel), supports 3.3 V microcontroller interfacing, operates up to 30 MHz clock frequency, and features balanced 100 ns rise/fall times for reduced system noise in high-density LED arrays.

For engineers reviewing the STP16CPC05MTR datasheet, STP16CPC05MTR pinout, STP16CPC05MTR application, or STP16CPC05MTR equivalent, key selection criteria include output current accuracy (±1.5% between bits), 20 V output voltage capability, thermal protection at 170 °C, SO-24 package compatibility, and R_EXT-based current programming for brightness control.

Technical Context

The device integrates a 16-bit shift register cascaded with a 16-bit D-type storage latch, enabling synchronous data loading and output latching via separate CLK and LE inputs. Its output stage uses sixteen matched regulated current sinks with programmable compliance up to 20 V, optimized for minimal turn-on/turn-off asymmetry.

Control logic includes active-low OE for global output disable, SDO for daisy-chaining multiple devices, and R_EXT terminal for precise current setting across all channels. Timing parameters are specified for both 3.3 V and 5 V supply operation, with setup/hold requirements validated for cascade configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
Output channels	16 independent constant-current sinks for LED anode-to-V_CC connections
Output current range	5–100 mA per channel, set by external R_EXT (200 Ω to 7.37 kΩ)
Max clock frequency	30 MHz - enables >4.8 Mbps serial data throughput for real-time display updates
Output voltage capability	20 V - supports series strings of up to 6 standard white LEDs (3.2 V VF each)
Current accuracy	±1.5% between bits at 25 °C - ensures uniform LED brightness across all 16 channels
Rise/fall time	108–150 ns (V_DD = 5 V) - minimizes switching-induced ringing in parasitic-inductive PCB layouts
Supply voltage range	3.0–5.5 V - compatible with both 3.3 V and 5 V logic domains without level shifting
ESD rating	2.5 kV HBM, 200 V MM - meets industrial handling requirements without additional protection circuitry

Pinout & Package

The STP16CPC05MTR is packaged in a 24-pin SOIC (SO-24) with standard 0.635 mm pitch, 15.2–15.6 mm body length, and 7.4–7.6 mm width. The exposed pad variant is not used in this MTR ordering code; thermal resistance is 60 °C/W junction-to-ambient.

Pin/Terminal	Circuit Role	Design Meaning
1 GND	Power ground reference	Common return path for all 16 output currents and internal logic; must be low-impedance
2 SDI	Serial data input	Accepts 3.3 V–compatible CMOS-level data for shift register loading
3 CLK	Shift clock input	Positive-edge-triggered; max 30 MHz; controls bit advancement into shift register
4 LE	Latch enable input	Transfers 16-bit data from shift register to output latches on rising edge
5–20 OUT0–OUT15	Constant-current output sinks	Each drives LED cathodes; current magnitude set globally by R_EXT
21 OE	Output enable (active low)	Pulls all outputs OFF when high; enables PWM dimming via external controller
22 SDO	Serial data output	Provides daisy-chain capability; outputs bit shifted out of last stage
23 R-EXT	Current-setting resistor terminal	Connects to external resistor to program identical output current across all 16 channels
24 VDD	Positive supply input	Supplies internal logic and output stage; decoupling capacitor required near pin

Key Features

Feature	Design Value
Balanced output timing	100 ns typical rise/fall symmetry reduces EMI and eliminates need for large bypass capacitors in LED string layouts
20 V output compliance	Enables driving longer LED strings (e.g., 6× white LEDs @ 3.2 V VF) without external boost circuitry
3.3 V logic compatibility	Direct interface with modern microcontrollers and FPGAs without level translators or pull-up resistors
Thermal shutdown	170 °C junction protection prevents damage during sustained overcurrent or poor heatsinking
Daisy-chain support	SDO pin allows cascading multiple STP16CPC05MTRs for >16-channel systems using single SPI bus

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-channel constant-current LED driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLC59283RTJR	Higher max current (120 mA), but only ±3% channel matching; no thermal shutdown	Requires external thermal monitoring; better suited for high-brightness outdoor signage	Select when peak current >100 mA is mandatory and thermal margin is guaranteed by system design
IS31FL3728-QFLS4-TR	I²C interface instead of SPI; integrated PWM grayscale control; 28 channels	Eliminates need for external microcontroller bit-banging; supports per-channel brightness scaling	Select when system uses I²C infrastructure and requires dynamic dimming without external PWM generation

Compared with TLC59283RTJR and IS31FL3728-QFLS4-TR, the STP16CPC05MTR offers superior current matching (±1.5% vs ±3% or ±6%), built-in thermal protection, and simpler SPI-based control-making it optimal for cost-sensitive, noise-sensitive LED panel designs where precision and robustness outweigh protocol flexibility.

FAQ

What is the minimum recommended R_EXT value for STP16CPC05MTR?

The minimum recommended R_EXT is 200 Ω, which sets the maximum output current to 100 mA per channel at V_DD = 5 V. Using lower values risks exceeding absolute maximum ratings and may trigger thermal shutdown. Data sheet Table 9 confirms 200 Ω yields 100 mA nominal output.

Can STP16CPC05MTR drive LEDs with forward voltage above 5 V?

Yes - the device guarantees 20 V output voltage capability, allowing it to drive LED strings totaling up to 20 V forward drop (e.g., six 3.2 V white LEDs). This is verified in Absolute Maximum Ratings (Table 3, V_O = –0.5 to 20 V) and Recommended Operating Conditions (Table 5, V_O = 20 V).

Does STP16CPC05MTR support daisy-chaining, and how many devices can be cascaded?

Yes - the SDO pin enables daisy-chaining. While no hard limit is specified, timing analysis (Table 7, t_PLH/t_PHL) shows cumulative propagation delay increases linearly; ST recommends limiting cascades to ≤5 devices for reliable 30 MHz operation with standard PCB trace lengths and load capacitance.

Is thermal pad connection required for STP16CPC05MTR in SO-24 package?

No - the SO-24 variant (MTR suffix) does not feature an exposed thermal pad. Thermal resistance is specified as 60 °C/W junction-to-ambient (Table 4); adequate PCB copper area under the package body is sufficient for typical 16 × 20 mA operation at +85 °C ambient.
