SPD1179

Product Introduction

SPD1179 is a motor control SoC for 12V automotive BDC and BLDC applications. It integrates MCU, current mode pre-driver, multiple LDOs and LIN transceiver. It incorporates a 32-bit ARM® Cortex-M4F core with 100 MHz, 32 KB SRAM, 128 KB embedded flash with up to 1 KB EEPROM emulated by extra 12 KB flash, and an extensive range of enhanced I/Os and peripherals. The device offers a 13-bit ADC, one differential PGA and one single-ended PGA, four enhanced PWMs, three general-purpose 32-bit timers, as well as standard and advanced communication interface: two UARTs with LIN support, two SPIs, one I2C and one CAN. The SPD1179 operates with a single power supply from 5.5V to 28V (42V for load dump) and supports stop/sleep mode for power saving. It integrates two 5V LDOs for internal power system and external sensor, and also integrates 3.3V and 1.2V LDOs for MCU operation. It supports 5V I/O for logic and 3.3V I/O for analog input channel. The junction temperature range is from -40 ⁰C to +150⁰C. The package type is 48-pin wettable flank QFN or 56-pin QFN. The SPD1179 employs function safety features such as backup clocking scheme, watchdog timer interrupt and reset, open/short detection and background critical voltage monitoring.
