E52002A Multi-Channel Low-Side Driver IC – 12-Channel Relay Driver for Body Control Modules

The E52002A is a highly integrated low-side driver IC specifically designed for automotive body control module applications.
This versatile driver controls up to twelve low-side switched relays, making it ideal for body convenience and lighting control systems.
The device autonomously generates a constant relay holding current across a wide supply voltage range without the need for external controller intervention.
A specialized internal circuit generates a PWM duty cycle that automatically compensates for changes in the supply voltage, ensuring consistent performance.
Configuration and control of all channels are managed through a standard SPI interface for seamless microcontroller integration.
Each of the twelve high-current outputs features a typical on-resistance of just 1.5Ω and supports up to 350mA maximum current.
The device offers comprehensive protection with short-circuit and over-temperature detection, along with error read-back capability for system diagnostics.
Switch monitoring is simplified with a single-wire control lamp combination output for efficient status reporting.
The ultra-low standby current of less than 1µA minimizes battery drain when the system is in idle or sleep mode.
Operating across a junction temperature peak of up to 150°C, this IC delivers reliable performance under demanding under-hood conditions.
Qualified to automotive-grade standards, this driver provides the durability required for modern vehicle body control and convenience applications.
For relay driver boards requiring low power dissipation and high integration, this device offers an efficient and robust solution.
