Product details
Overview
LP5560TME/NOPB from Texas Instruments is a programmable single-LED driver IC with high-side constant-current output, single-wire digital control interface, 40 mV typical headroom voltage, adjustable LED current (2.8–19.5 mA), and programmable blink sequences up to three pulses - used for indicator feedback in portable consumer electronics.
For engineers reviewing the LP5560TME/NOPB datasheet, LP5560TME/NOPB pinout, LP5560TME/NOPB application, or LP5560TME/NOPB equivalent, this page delivers verified electrical parameters, confirmed DSBGA-4 package mapping, validated terminal roles, real-world timing behavior (e.g., 105.6 ms rise/fall time resolution), and two documented alternative drivers for indicator LED systems requiring ultra-low-headroom, no-external-component operation.
Technical Context
The LP5560TME/NOPB implements a volatile-programmable state machine controlled via a single-wire interface with fixed VIH/VIL thresholds (1.1 V / 0.6 V), supporting four command types (Run, Training Start, Training End, Run Once) based on rising-edge counts during a defined command-entering period. Its internal high-side current source regulates LED current without external components.
It features factory-default blinking sequence storage, mode-bit-controlled operation (Follow Mode vs Run Mode), and training-based parameter programming for rise time, on/off duration, and fall time - all executed using calibrated pulse-width encoding referenced to a user-defined TCAL (350 µs–8 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports direct battery connection (e.g., Li-ion, coin cell) without LDO or boost stage. |
| LED Output Current | 2.8 mA to 19.5 mA in 8 discrete steps - enables brightness tuning across diverse indicator LEDs. |
| Headroom Voltage | 40 mV typical at 5.3 mA - allows driving common red/green/blue indicator LEDs directly from 2.8 V+ supplies. |
| Rise/Fall Time Resolution | 105.6 ms step size, 0–1584 ms range - provides granular fade control for soft visual transitions. |
| On/Off Time Range | On: 13.2–3009.6 ms; Off: 26.4–6019.2 ms - supports short alerts and long-status indicators in same device. |
| Interface Protocol | Single-wire, edge-counted, no clock line - reduces GPIO count and PCB routing complexity in space-constrained designs. |
| Shutdown Current | 0.4–0.75 µA - ensures negligible battery drain when LED is inactive in always-on portable devices. |
Pinout & Package
LP5560TME/NOPB uses Texas Instruments' 4-pin DSBGA (YFQ) package, 0.886 mm × 0.886 mm body size, 0.4 mm pitch, bottom-solder-ball termination - optimized for ultra-compact portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Supplies internal bias and LED drive current path; accepts 2.7–5.5 V with UVLO at 2.3 V. |
| LED | High-side current source output | Connects to anode of indicator LED; sinks regulated current to GND through cathode. |
| GND | Ground reference | Return path for LED current and internal circuitry; must be low-impedance for stable regulation. |
| CTRL | Digital control input | Single-wire interface pin; interprets rising edges for command entry (Run/Training/Run Once) and mode control. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small solution size | No external resistors, capacitors, or inductors required - reduces BOM count and board area in wearables and card readers. |
| Programmable multi-pulse sequence | Up to three independent LED pulses per sequence, each with configurable rise/on/fall/off timing - enables complex status signaling (e.g., charging progress, error codes). |
| Factory-default blink pattern | Pre-programmed sequence enables immediate LED indication without firmware or host controller - ideal for simple systems like fuel dispensers or access cards. |
| Low-voltage compatible interface | CTRL pin VIH = 1.1 V min, VIL = 0.6 V max - interoperates with 1.8 V logic microcontrollers without level shifters. |
| Volatile memory architecture | Blinking parameters stored in volatile RAM - resets to default on power cycle, simplifying initialization and avoiding persistent misconfiguration. |
Applications
| Cell Phone Indicator | Card Reader Status |
|---|---|

Use Value: Supports differentiated visual alerts using one GPIO and minimal PCB space - critical for compact, tamper-resistant enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LP55231RTER | 3-channel, I²C interface, 1.7–5.5 V supply, 0.5–25 mA per channel - requires external I²C lines and more board area. | Supports RGB LED control and synchronized multi-LED effects; not suitable for single-LED, pin-constrained use cases. | Select when multi-color sequencing or host-controlled dynamic updates are required; avoid if single-wire simplicity is mandatory. |
| MAX77691EWL+T | 4-channel, I²C, integrated boost converter, 0.1–25 mA per channel - includes power management but adds complexity and cost. | Enables driving higher-Vf LEDs (e.g., white) from low-voltage sources; over-engineered for basic indicator use. | Choose only when LED forward voltage exceeds system rail (e.g., >3.6 V) and boost capability is needed; otherwise, LP5560TME/NOPB offers lower BOM and layout cost. |
Compared with LP5560TME/NOPB, LP55231RTER adds channel count and I²C flexibility at the expense of pin count and software dependency, while MAX77691EWL+T integrates power conversion for high-Vf LEDs but increases footprint and design complexity - making LP5560TME/NOPB optimal for cost-sensitive, space-limited single-LED indicator systems.

FAQ
What is the function of the CTRL pin on the LP5560TME/NOPB?
The CTRL pin on the LP5560TME/NOPB serves as the sole digital interface for mode control and programming. It detects rising edges to execute commands (Run, Training Start, Training End, Run Once), sets Follow or Run Mode via training sequence, and triggers LED current setting and timing parameter configuration - all without clocks or bidirectional data lines.
Does the LP5560TME/NOPB require external components for basic operation?
No, the LP5560TME/NOPB requires zero external components for core functionality. Its integrated high-side current source, internal oscillator, and volatile memory eliminate the need for current-setting resistors, timing capacitors, or external crystals - enabling a complete LED driver solution in under 0.8 mm² PCB area.
How does the LP5560TME/NOPB handle power supply variations?
The LP5560TME/NOPB maintains LED current regulation across 2.7–5.5 V input with ±3%/V line regulation and <1% load regulation over 1.7–3.4 V LED forward voltage. Its 40 mV headroom voltage ensures stable output even as battery voltage declines, and undervoltage lockout disables operation below 2.3 V to prevent erratic behavior.
Can the LP5560TME/NOPB drive multiple LEDs simultaneously?
No, the LP5560TME/NOPB is a single-channel LED driver with one high-side current output (LED pin). It is designed exclusively for driving one indicator LED. For multi-LED applications, TI recommends alternatives such as the LP55231RTER or LP5562, which provide multiple independent channels with synchronized control.
What happens to programmed sequences during power cycling of the LP5560TME/NOPB?
Programmed sequences in the LP5560TME/NOPB are stored in volatile memory and reset to the factory-default blink pattern upon power loss or VDD ramp-down. This ensures predictable startup behavior without firmware intervention and prevents unintended LED activity after brownout or cold start.
