MA7020/B屬于高耐壓高溫雙極鎖存霍爾開(kāi)關(guān)，適用于流量計(jì)計(jì)數(shù)，無(wú)刷電機(jī)換相，筋膜槍?zhuān)绷黠L(fēng)扇電機(jī)換相。
GENERAL DESCRIPTION
MA7020/B is an integrated Hall effect latched sensor designed for electronic commutation of b-less DC motor applications. The device is using HV BCD process includes an on-chip
Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a
Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An
internal band-gap regulator is used to provide temperature compensated supply voltage for
internal circuits and allows a wide operating supply range.
If a magnetic flux density larger than threshold Bop, OUT is turned on(low). The output state is held until a magnetic flux density reversal falls below Brp causing OUT to be turned off (high).
FEATURES
- 2.5V to 26V DC operation voltage
- Temperature compensation
- Wide operating voltage range
- Open-Drain pre-driver
- 25mA maximum sinking output current.
- Low Profile TSOT/SOT23-3L and SIP-3L(TO-92S) Package( Green and Lead Free )
