A80601KESJSR Description

The A80601KESJSR is a multi-output LED driver for automotive applications such as exterior lighting, heads-up display, and midsize LCD backlighting. 

A80601KESJSR Features

• Automotive AEC-Q100 qualified

• Enhanced fault handling for ASIL B system compliance

• Wide input voltage range of 4.5 to 40 V for start/stop, cold crank, and load dump requirements

• Operate in Boost or SEPIC mode for flexible output

• Gate driver for external NMOS to deliver higher output power

• Four integrated LED current sinks, up to 210 mA each

• Boost switching frequency synced externally or programmed from 200 kHz to 2.3 MHz

• Programmable boost frequency dithering to reduce EMI

• Advanced control allows minimum PWM on-time down to 0.3 µs, and avoids MLCC audible noises

• LED contrast ratio: 15,000:1 at 200 Hz using PWM dimming alone, 150,000:1 when combining PWM and analogue dimming

• Excellent input voltage transient response even at the lowest PWM duty cycle

• Gate driver for optional PMOS input disconnect switch

• Extensive fault protection features
