The TLV370x is Texas Instruments’ first family of nanopower comparators with only 560 nA per channel supply current, which make this device ideal for low power applications.

The TLV370x has a minimum operating supply voltage of 2.7 V over the extended temperature range
(TA = –40°C to 125°C), while having an input common-mode range of –0.1 to VCC + 5 V. The low supply current makes it an ideal choice for low power applications where quiescent current is the primary concern. Reverse battery protection guards the amplifier from an over-current condition due to improper battery installation. For harsh environments, the inputs can be taken 5 V above the positive supply rail without damage to the device.

Devices are available in SOIC with the singles in the small SOT-23 package. Other package options may be made available upon request.

CIRCUIT060074 — 采用比较器的高侧电流检测电路

该高侧电流检测解决方案使用一个具有轨到轨输入共模范围的比较器,如果负载电流上升至超过 1A,则在比较器输出端 (COMP OUT) 产生过流警报 (OC-Alert) 信号。该实现中的 OC-Alert 信号低电平有效。因此,当超过 1A 阈值后,比较器输出变为低电平。实现了迟滞,使得当负载电流减小至 0.5 A(减少 50%)时,OC-Alert 将返回到逻辑高电平状态。该电路使用漏极开路输出比较器,从而对输出高逻辑电平进行电平转换,以控制数字逻辑输入引脚。对于需要驱动 MOSFET 开关栅极的应用,最好使用具有推挽输出的比较器。
