TLV840 Nano-Power Ultra-Low Voltage Supervisor with Adjustable Reset Time Delay

1 Features

3 Description

•

Operating voltage range : 0.7 V to 6 V

Nano supply current : 120 nA (Typical)

Fixed threshold voltage (V_IT-): 0.8 V to 5.4 V

– Threshold voltages available in 100mV steps

– High accuracy: ±0.5% (Typical)

– Built-in hysteresis (V_HYS): 5% (Typical)

Reset time delay (t_D): capacitor-based

programmable (TLV840C, TLV840M)

– Minimum time delay: 40 µs (typical) without

capacitor

The TLV840 family of voltage supervisors or reset ICs

can operate at high voltage levels while maintaining

very low quiescent current across the whole VDD and

temperature range. TLV840 offers best combination of

low power consumption, high accuracy and low

propagation delay (t_{p_HL}= 30 µs typical).

Reset output signal is asserted when the voltage at

VDD drops below the negative voltage threshold

(V_IT-). Reset signal is cleared when VDD rise above

V_IT-plus hysteresis (V_HYS) and the reset time delay

(t_D) expires. Reset time delay can be programmed by

connecting a capacitor between the CT pin and

ground for TLV840C and TLV840M. For a minimum

reset delay time the CT pin can be left floating.

TLV840N does not offer a programmable delay and

offers fixed reset delay timing options: 40 µs, 2 ms, 10

ms, 30 ms, 50 ms, 80 ms, 100 ms, 150 ms, 200 ms.

•

Active-low manual reset (MR) (TLV840M)

Four output topologies:

– TLV840xxDL: open-drain, active-low (RESET)

– TLV840xxPL: push-pull, active-low (RESET)

– TLV840xxDH: open-drain, active-high (RESET)

– TLV840xxPH: push-pull, active-high (RESET)

Wide temperature range: –40°C to +125°C

Package: SOT23-5 (DBV)

•

Additional features: Low power-on reset voltage

(V_POR), built-in glitch immunity protection for VDD,

built-in hysteresis, low open-drain output leakage
