The A1333LLPTR-DD-T is a dual-die, 24-pin eTSSOP packaged Hall-effect angle sensor IC designed for safety-critical automotive applications, providing contactless 0° to 360° position, speed, and direction measurement via circular vertical Hall technology. It supports ASIL D compliance when used as a hardware safety element out-of-context per ISO 26262, features on-chip EEPROM for calibration, 10 MHz SPI, and ABI/UVW outputs. The device operates from 4.0 to 16.5 V, with an extended junction temperature range of -40°C to 150°C, and is rated for direct 12 V battery connection and ISO 7637-2 Pulse 5b up to 39 V. Dual-die stacking improves die-to-die matching for redundancy applications.
The A1333 provides high-resolution angle measurements with integrated diagnostics for safety-critical applications. Supports various output formats (UVW, ABI, SPI, PWM) and on-chip EEPROM for flexible configuration.
