Allegro MicroSystems Inc. Automotive Multiple Output Regulator A8600EJPTR-T

Description
Designed to provide the power supply requirements of next generation car audio and infotainment systems, the A8600 provides all the control and protection circuitry to produce four high current regulators, each with ±1.5% accuracy. The A8600 includes control circuitry to implement three adjustable, asynchronous buck regulators with integrated MOSFETs. Also, the A8600 provides the control circuitry, gate drivers, and current sensing to implement a synchronous buck controller with external MOSFETs. In standby mode, the A8600 draws less than 50 μA from VIN of 12 V while employing pulse frequency modulation (PFM) to deliver 3.3 V/40 μA via the always-on regulator, SW1. The always-on regulator operates down to at least VIN of 3.6 V (VIN falling). Features of the A8600 include: an EN/SYNC input to either turn the A8600 on/off or increase/decrease the base pulse width modulation (PWM) frequency, four adjustable soft-start times, and four external compensation pins. Output voltage monitoring of switchers SW2, SW3, and SW4 is provided by a single, open-drain POK output. In addition, the A8600 provides two high voltage, high-side switches with foldback overcurrent protection. These two high-side switches actively block reverse current. The A8600 also provides direct battery (BU) and switched (accessory) battery (ACC) detectors and a mute pulse output with an adjustable delay. Protection features of the A8600 include pulse-by-pulse current limit, hiccup mode short circuit protection, asynchronous diode protection, BOOT voltage protection, undervoltage lockout, overvoltage protection and thermal shutdown. The A8600 is supplied in a low profile 48-pin LQFP package (suffix JP ) with exposed power pad. It is lead (Pb) free, with 100% matte tin leadframe plating. Major Features
