Description

LP5910-1.8DRVR is a small, constant-current LED driver IC used to drive one LED string from a single supply. It regulates the LED current via an external sense resistor, keeping the current stable despite supply or LED forward‑voltage changes. Features usually include open/short-LED protection, thermal shutdown, and dimming support (PWM or analog). It’s packaged in a tiny surface‑mount package suitable for battery-powered indicators, backlights, and small display LEDs. The “-1.8” suffix denotes a variant; exact electrical specs (LED current, input range, pinout) vary by revision. For precise values and application guidelines, consult the official LP5910-1.8DRVR datasheet and reference designs.

Features

LP5910-1.8DRVR features (concise):
- 1.8V input operation for low-voltage systems
- Constant-current LED driver for a string
- External resistor sets adjustable LED current
- Dimming compatibility: PWM and analog dimming (DIM/EN)
- Protection: open-load and short-circuit protection
- Over-temperature (thermal) shutdown and current limit
- Soft-start to reduce inrush and flicker
- Low quiescent current for high efficiency
- Small package (surface-mount, compact footprint)
- Suitable for backlighting and indicator LEDs in portable/applications
Note: specifics (e.g., current range, voltage limits) vary by revision; refer to the exact datasheet for exact pins and electrical characteristics.

Pinout

- Pin count: Typical 8 pins (SOP-8 / SOIC-8 package; exact pinout depends on package variant).
- Function: 1.8V LED driver (constant-current driver) with control/interface pins for enabling and programming the LED current.
Note: exact pinout and features depend on the specific package and revision—refer to the datasheet for the precise pin assignments.

Application

LP5910-1.8DRVR is a fixed 1.8V LDO regulator/driver. Typical applications include:
- Generation of the 1.8V core rail for digital ICs (CPU/GPU, memory, FPGA/ASIC)
- Power supply for portable/embedded devices (cell phones, tablets, wearables, cameras)
- RF/analog front-end circuits requiring a clean 1.8V supply
- Power-management blocks in consumer electronics (set‑top boxes, displays, modems)
In short: a compact, low-noise 1.8V regulator suitable for 1.8V domains in various digital and mixed-signal systems.

Package

LP5910-1.8DRVR is in an 8-pin MSOP package (MSOP-8).
