NM18002 Datasheet | Nuvoton Technology

DESCRIPTION The NM18002 series is embedded with an 8-bit high performance 1T 8051-based microcontroller and a monolithic H-bridge gate driver for driving high-side P-channel and low-side N-channel power MOSFETs. It is designed for single phase BDC or BLDC motor driver applications which operate up to 28V. The 8-bit MCU provides rich peripherals including 256 bytes of SRAM, 1K bytes of auxiliary RAM (XRAM), 16K bytes of APROM, 1K bytes of LDROM, 128 bytes of SPROM, up to 9 general purpose I/O, two 16-bit Timers/Counters 0/1, one 16-bit Timer2 with three-channel input capture module, one Watchdog Timer (WDT), one Self Wake-up Timer (WKT), one 16-bit auto-reload Timer3 for general purpose or baud rate generator, two UART, one I2C, INT0, GPIO interrupt and one 12-bit ADC with 4 inputs. The peripherals are equipped with 18 sources with 4-level-priority interrupts capability. This gate driver integrates a 5V linear voltage regulator with maximum 50m A output current capability and an Under Voltage Lock Out (UVLO) circuit which prevents malfunction when VCC is lower than the specified threshold voltage. It provides two sets of analog parator(ACMP) for the signal conditioning of the Hall sensors and the shunt resistor signal. Besides, there is an embedded open-drain output which can transfer the low-voltage signal to high voltage by external pull-up resistor to VCC. Additionally, the NM18002 series is equipped with ISP (In-System Programming) and ICP (In Circuit Programming) functions, which allow the user to update the program memory without removing the chip from the actual end product. NM18002 is the bination of MCU MS51FB9AE and Gate Driver NCT3620. User may refer to the TRM of MS51FB9AE and the datasheet of NCT3620 for the detailed specification. The MS51FB9AE BSP is also for NM18002 software developing.
