UJA1167
Mini high-speed CAN system basis chip with Standby/Sleep modes &
watchdog
Battery and CAN bus pins protected against automotive transients according to
ISO 7637-3
Very low quiescent current in Standby and Sleep modes with full wake-up capability
Leadless HVSON14 package (3.0 mm 4.5 mm) with improved Automated Optical
Inspection (AOI) capability and low thermal resistance
Dark green product (halogen free and Restriction of Hazardous Substances (RoHS)
compliant)
2.3 Low-drop voltage regulator for 5 V microcontroller supply (V1)
5 V nominal output; 2 % accuracy
100 mA output current capability
Current limiting above 150 mA
On-resistance of 5 (max)
Support for microcontroller RAM retention down to a battery voltage of 2 V
Undervoltage reset with selectable detection thresholds: 60 %, 70 %, 80 % or 90 % of
output voltage
Excellent transient response with a 4.7 F ceramic output capacitor
Short-circuit to GND/overload protection on pin V1
Turned off in Sleep mode
2.4 Power Management
Standby mode featuring very low supply current; voltage V1 remains active to maintain
the supply to the microcontroller
Sleep mode featuring very low supply current with voltage V1 switched off
Remote wake-up capability via standard CAN wake-up pattern
Local wake-up via the WAKE pin
Wake-up source recognition
Local and/or remote wake-up can be disabled to reduce current consumption
High-voltage output (INH) for controlling an external voltage (UJA1167TK)
2.5 System control and diagnostic features
Mode control via the Serial Peripheral Interface (SPI)
Overtemperature warning and shutdown
Watchdog with independent clock source
Watchdog can be operated in Window, Timeout and Autonomous modes
Optional cyclic wake-up in watchdog Timeout mode
Watchdog automatically re-enabled when wake-up event captured
Watchdog period selectable between 8 ms and 4 s
Supports remote flash programming via the CAN bus
16-, 24- and 32-bit SPI for configuration, control and diagnosis
Bidirectional reset pin with variable power-on reset length to support a variety of
microcontrollers
Configuration of selected functions via non-volatile memory
