TPL5000 datasheet

Description

The TPL5000 is a long-term timer IC optimized for low power applications. The TPL5000 can replace a micro controller’s (µC) internal timer, allowing the µC to stay in low power sleep mode instead of running a timer, providing a total power consumption reduction of 60 to 80%.

The device is designed for use in interrupt-driven applications and provides selectable timing from 1 second to 64 seconds. Some Standards (i.e. EN50271) require implementation of a watchdog function for safety.

Features

1. Supply Voltage from1.8 V to 5.0 V

2. Current Consumption 30 nA (typical, at 2.5 V)

3. Watchdog Functionality

4. Reset Functionality

5. Selectable Timer Intervals 1 to 64 s

Features

1. Front panel mounting
2. Width 45mm
3. 8 functions
4. 1 change over contact

Functions

1. ON delay (A)

When the supply voltage U is applied, the value of the time already expired is cleared and the set time t begins to run (display for time lapse flashes, counting runs either by adding or subtracting). After expiry of the time t, the output relay R picks up (OP display lights up) and the set time t (adding) or the value 0 (subtracting) is shown in the display. The status is maintained until the supply voltage is interrupted
