Why the SL2044 PMIC by SLKOR Is Reshaping Power Management in Automotive, IoT, and Industrial Applications

Description
 The SL2044 integrated circuit is specifically designed for automotive steering lamp control systems managed by relays. Featuring two independent output ports, it can separately control both left and right turn signal relays. The control inputs require only minimal current, allowing for the use of low-power switches as automotive steering controls. Additionally, the IC includes a dedicated failure warning input, simplifying the overall warning signal control circuitry. When a lamp failure is detected, the SL2044 automatically doubles the flashing frequency, providing a clear visual alert. Thanks to its ultra-low standby current (<10µA), the device can be directly connected to the vehicle’s battery, ensuring continuous reliability.
