Product Description:
YJJ SS441R Single-Ended Digital Hall Switch Non-contact Magnetic Detection General Chip
Features:
Model: SS441R
Type: Single-pole digital Hall switch (high sensitivity), part of the SS440R series, only responding to the south pole (S pole) of the magnetic field, TO-92 surface-mount package, industrial-grade wide temperature range, built-in protection, non-contact magnetic detection universal chip.
I. Basic Overview
Product classification: Single-polarity digital Hall effect switch (Unipolar Hall Switch)
Response magnetic pole: Only the south pole (S pole) triggers, no action on the north pole (N pole)
Sensitivity: Highest sensitivity in the same series (the highest among the three models in the SS440R series)
Package: Flat TO-92, 3-pin surface-mount, soldering, easy wiring
Output: NPN current-sink (pull-down) output, open-drain output, can directly drive MCU IO, transistors, relays
Built-in protection: Reverse power supply protection, no chip burnout due to reversed wiring
II. Core Magnetic Parameters (25℃ reference)
1Gs = 0.1mT
Typical operating point (Bop magnetic field conduction threshold): 75 G (7.5 mT)
Maximum conduction magnetic field: 135 G (13.5 mT)
Minimum release magnetic field (Brp deactivation threshold): 10 G (1.0 mT)
Magnetic hysteresis difference (Bop-Brp): Typical 40 G, anti-jitter, anti-mis-trigger
Detection characteristics: S pole close to conduction, magnetic field withdrawal disconnects, no latch-up
III. Complete Electrical Parameters
1. Power supply parameters
Working voltage range: 3.0 V ~ 24 V DC (compatible with 3.3V/5V/12V/24V systems)
Typical supply current: 4 mA (5V supply), maximum 8 mA
Maximum output current sink: 20 mA (open-drain output upper limit)
Leakage current: ≤10μA
2. Switching response characteristics
Output rise/fall time: ≤1.5 μs, high-speed switching
Operating temperature range: -40℃ ～ +150℃ (extremely wide industrial high-temperature grade)
Storage temperature: -55℃～165℃
Pin definition (TO-92 facing forward, pins facing down from left to right)
1 pin: VCC (power supply positive pole)
2 pin: GND (power supply ground)
3 pin: OUT (NPN open-drain output)
