Part Number: LM5060-Q1

Function: High-Side Protection Controller with Low Quiescent Current

Package: VSSOP 10 Pin Type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The LM5060-Q1, LM5060 high-side protection controller provides intelligent control of a high-side N-Channel MOSFET during normal on/off transitions and fault conditions.

In-rush current is controlled by the nearly constant rise time of the output voltage. A power good output indicates when the output voltage reaches the input voltage and the MOSFET is fully on.

Input Under-Voltage Lock-Out, with hysteresis, is provided as well as programmable input Over-Voltage Protection.

Features

1. Less than 15-µA quiescent current in disabled mode

2. Controlled output rise time for safe connection of capacitive loads

3. Charge pump gate driver for external N-Channel MOSFET

4. Adjustable Undervoltage Lockout (UVLO) with hysteresis

Description

The AH285 is a single-chip solution for driving two-coil brushless direct current (BLDC) fans and motors. The device includes a Hall-effect sensor, dynamic offset correction and two complementary open-drain output drivers with internal Zener diode protection.

To help protect the motor coils, the AH285 provides Rotor Lock Protection which shuts down output drives if rotor lock is detected. The device automatically re-starts when the rotor lock is removed.

A Tachometer output is provided by open-drain Frequency Generator (FG) Pin which allows external interface to monitor motor rotation or speed. The FG output is the magnetic change frequency.

Features

1. Single-chip solution

2. Operating Voltage: 3.8V to 20V

3. Built-in Hall sensor and input amplifier

4. Tachometer (FG) output

5. Rotor Lock Protection (Lock detection, output shutdown and automatic re-start)

6. Built-in Zener protection for output driver

7. Average output current up to 500mA

8. Green Molding Compound

 

Applications:

1. Two-coil BLDC Cooling Fans

2. Low to Medium Voltage, Low Power BLDC Motors
