NCV8870

Automotive Grade Non-Synchronous Boost Controller NCV8870 The NCV8870 is an adjustable output non−synchronous boost controller which drives an external N−channel MOSFET. The device uses peak current mode control with internal slope compensation. The IC incorporates an internal regulator that supplies charge to the gate driver. Protection features include internally−set soft−start, undervoltage lockout, cycle−by−cycle current limiting, hiccup−mode short−circuit protection and thermal shutdown. Additional features include low quiescent current sleep mode and externally−synchronizable switching frequency. Features  Peak Current Mode Control with Internal Slope Compensation  1.2 V 2% Reference voltage  Fixed Frequency Operation  Wide Input Voltage Range of 3.2 V to 40 Vdc, 45 V Load Dump  Input Undervoltage Lockout (UVLO)  Internal Soft−Start  Low Quiescent Current in Sleep Mode  Cycle−by−Cycle Current Limit Protection  Hiccup−Mode Overcurrent Protection (OCP)  Hiccup−Mode Short−Circuit Protection (SCP)  Thermal Shutdown (TSD)  NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable  This is a Pb−Free Device DATA SHEET www.onsemi.com SOIC−8 D SUFFIX CASE 751 MARKING DIAGRAM 8 8870xxG ALYW G 1 (Top View) 8870xxG = Specific Device Code xx = 01 A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package PIN CONNECTIONS EN/SYNC 1 ISNS 2 GND 3 GDRV 4 ...
