Product Overview
A1120EUA-T is a chopper-stabilized precision hall-effect unipolar switch. It is extremely temperature-stable and stress-resistant sensor IC, especially suited for operation over extended temperature ranges to 150°C. Superior high temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress. It includes on a single silicon chip a voltage regulator, Hall-voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short-circuit protected open-drain output to sink up to 25mA. An on-board regulator permits operation with supply voltages of 3 to 24V. The advantage of operating down to 3 V is that the device can be used in 3 V applications or with additional external resistance in series with the supply pin for greater protection against high-voltage transient events.
- Voltage output, 1D planar type
- Supply voltage range from 3 to 24V
- AEC-Q100 automotive qualified
- Unipolar switch points, resistant to physical stress
- Superior temperature stability, output short-circuit protection
- Operation from unregulated supply, reverse-battery protection
- Solid-state reliability, small package sizes
- Supply current is 4mA max (VCC = 12V, B > BOP
- Zener impedance is 50 ohm typ (ICC = 5mA, TA = 25°C)
- 3 pin SOT23W package, operating temperature range from -40 to 150°C
Footnotes
3 The chopper-style UA package is not for new design; the matrix HD style UA package is recommended for new designs
