Description and Introduction

9-Output LED Driver with Intensity Control and Hot-Insertion Protection The MAX6965AEE+ is a 4-wire serial-interfaced LED driver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX6965AEE+  
- **Type:** LED Driver  
- **Interface:** 4-wire serial (SPI-compatible)  
- **Number of Outputs:** 8 constant-current sink outputs  
- **Output Current:** Adjustable (up to 55mA per output)  
- **Supply Voltage:** 3V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QSOP  

### **Descriptions:**
The MAX6965AEE+ is an LED driver designed for driving LEDs in applications requiring constant-current sink outputs. It features a 4-wire serial interface (SPI-compatible) for easy microcontroller integration. The device allows individual brightness control for each LED through PWM dimming. It is suitable for applications such as backlighting, signage, and general LED display control.

### **Features:**
- **8 Constant-Current Sink Outputs:** Each output can drive LEDs independently.  
- **Adjustable Current:** Output current programmable via an external resistor.  
- **PWM Dimming Control:** Individual 8-bit PWM brightness control for each output.  
- **Low-Power Shutdown Mode:** Reduces power consumption when not in use.  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Compact Package:** 16-pin QSOP for space-constrained applications.

Alternative Part Number

  • PCA9535PW --: 16-bit I2C I/O expander with similar GPIO expansion function and interrupt output, widely available and pin-compatible in function.
  • TCA9535PWR --: 16-bit I2C/SMBus I/O expander offering equivalent GPIO expansion and interrupt capability, direct functional substitute.
  • PCF8575TS --: 16-bit I2C I/O expander with open-drain outputs, suitable alternative for LED driving and keypad scanning applications.
  • PCA9555PW --: 16-bit I2C I/O expander with interrupt output, functionally similar to the MAX6965 and widely available in TSSOP.
  • TCA9555PWR --: Pin-compatible I2C I/O expander family with interrupt, good drop-in substitute for LED/GPIO expansion applications.
