LV8099CS Constant-current Driver IC

I2C SCL input pin Enable & reset *1, 2 Ground I2C SDA input pin Power supply pin Output pin A 0.4 0.87 B B1 B2 B3 1.27 *1 : Setting the ENA pin to low powers down and resets the IC. It is necessary to power on the IC by setting the ENA pin to low and hold it high during normal operation. *2 : When the ENA pin is to be used with pull_up, it is necessary t.

Features

current control enabled by DAC (10 bits). 2
• I C bus control supported.
• Wide operating voltage range (2.2 to 5.0V).
• Built-in current detection resistor.
• 6-pin WLP package used (1.27 × 0.87 × 0.5mm).
• Built-in voltage drop protection circuit (VCC = 2V output off).
• Built-in thermal protection circuit.
• Low output block total-resistance of 2Ω helps withstand voltage drop in VCC. (Current detection resistance + output transistor on-resistance).
• Built-in VCM overshoot preventive function (current slope function). Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum .
