SPD1148

Product Introduction

SPD1148 is a SiP (System in a Package) device integrating MCU, Pre-Driver module and power management module, targeting BLDC motor driving application with supply voltage up to 42V. The MCU incorporates a 32-bit ARM Cortex-M4 with clock rate as high as 200 MHz, 64 KB SRAM, embedded flash with 128 KB, and an extensive range of enhanced I/Os and peripherals. The device offers a 14-bit ADC, three PGAs, six enhanced PWMs, three general purpose 32-bit timers, as well as standard and advanced communication interface. The Pre-Driver module provides three half-bridge pre-drivers, with programmable charging /discharging current capability up to 1A. Integrated Charge Pump supports 100% duty cycle. The Power management module includes a 42V maximum input, 3.3V 300mA output buck DC-DC regulator, and Brown-out-Detection observing each of the power rail.
