FEATURES
GENERAL DESCRIPTION
ꢀ 22-bit Sigma-delta converter
ꢀ Six main sensor inputs
ꢀ One auxiliary input
ꢀ Supports CT or Rogowski Coils
ꢀ Internal di/dt integrators
ꢀ < 5 msec. startup time
The Teridian 71M6403 is an electronic trip unit (ETU) system-on-chip
device for air circuit breakers (ACB), molded case circuit breakers
(MCCB) and other types of intelligent switchgear. Utilizing Teridian’s
patented Single Converter Technology, the 71M6403 incorporates a
22-bit delta-sigma ADC, 7 current sensor inputs, digital temperature
compensation, precision voltage reference, 32-bit programmable
computation engine, timers, Real Time Clock (RTC), two UARTs and a
single cycle execution 8-bit MCU.
ꢀ Better than 10ppm/°C accuracy
ꢀ Instantaneous and delay trip
ꢀ Peak & RMS current measurement
Armed with an internal digital di/dt integrator, this programmable device
supports either current transformer (CT) or Rogowski-Coils for any or all
input channels and provides instantaneous and delayed over current,
earth-leakage, ground-fault and arc fault protection functions.
Furthermore, the device may be configured to support any number of
conventional or custom protection algorithms that fit specific load
configurations in the field.

ꢀ Power measurement functions
option
The 71M6403 also includes a 5V LCD charge pump as well as 3V LCD
support with up to 168 pixels display and up to 22 DIO pins. Easy
conversion to ROM offers unprecedented cost structure for high volume
MCCB applications.
ꢀ Internal temperature sensor
ꢀ Digital temperature compensation
ꢀ Independent 32-bit compute engine
ꢀ Two UART ports
ꢀ Two timers
ꢀ Hardware watchdog
A complete suite of in-circuit emulator (ICE) and development tools, a
powerful real-time signal monitoring tool, programming libraries and
reference designs enable rapid development of advanced switchgear.
ꢀ Internal power fault detector
ꢀ Real Time Clock (RTC)
ꢀ Battery backup (RTC, RAM)
