BU16501KS2-E2 is a product of PMIC – LED Drivers and it is an advanced inductive-load solution for driving LEDs with various current levels. This product integrates an internal PWM driver, a high-side N-channel MOSFET and a step-down controller for high efficiency and low noise operation. The BU16501KS2-E2 is ideal for automotive, industrial, and general lighting applications.

The BU16501KS2-E2 provides a high power factor and low total harmonic distortion. It offers excellent performance over wide temperature ranges. The product is also capable of operating at high ambient temperatures up to 150°C. It is also highly efficient with a wide input voltage range from 4.5V to 55V and is protected against surge voltages up to 65V. Additionally, the BU16501KS2-E2 comes with an additional protection pin to disable the LED output when an over voltage or over temperature is detected.

The BU16501KS2-E2’s integrated LED driver can be configured with a built-in digital dimming interface or a constant-current mode. In the constant-current mode, the LED current is controlled using the built-in induction limiting circuit, while in the digital dimming mode the LED current can be adjusted via the dimming interface. Both modes are capable of driving up to 15 LEDs in parallel.

The BU16501KS2-E2 also has a high tolerance towards transient overvoltage and a built-in over-voltage protection circuit. The product also comes with a low-side N-channel MOSFET for external inductive-loads. The device also integrates an internal voltage regulator and a VSS detector to provide a short circuit protection for the external load.

Moreover, the BU16501KS2-E2 provides a wide range of customizable options for the user. The user can select the desired LED current level (up to 1A), LED dimming rate, LED over temperature protection threshold, LED over voltage protection threshold, LED voltage regulation level and LED current regulation level.

The BU16501KS2-E2 also features a special power saving mode, which reduces the LED current to 30mA when the LED output is disabled. This mode is designed to reduce the power consumption in standby conditions, while still providing full protection against overvoltage and overtemperature.

Overall, the BU16501KS2-E2 is a highly efficient and integrated solution for driving all types of LEDs. It offers excellent performance over wide temperature ranges, wide input voltage range and is protected against surge voltages up to 65V. It also provides a wide range of customisable options and a power saving mode for reducing power consumption in standby conditions. The product is perfectly suited for automotive, industrial and general lighting applications.
