TPS389033DSET
TEXAS INSTRUMENTS TPS389033DSET 芯片, 电压监控器, 5.5V, WSON-6 新
The is a low quiescent current, 1% accurate supervisor with programmable delay in 6 pin WSON package. This precision voltage supervisor monitors system voltages as low as 1.15V, asserting an open-drain active-low RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset active-low MR pin drops to a logic low. The active-low RESET output remains low for user adjustable delay time after SENSE voltage and manual reset active-low MR return above respective thresholds. The TPS3890 uses a precision reference to achieve 1% threshold accuracy. The reset delay time can be user adjusted between 40µs and 30s by connecting CT pin to an external capacitor. The TPS3890 has a very low quiescent current of 2.1µA. It is typically used in battery powered and space constrained applications.
