描述

The MAX16163 and MAX16164 are nanopower on/off controllers with programmable sleep time. The devices integrate a power switch to gate an output, which provides up to 200mA load current.

The MAX16163/MAX16164 use either an external resistor to program the sleep time or program the sleep time through an I2C bus. When the device powers up, it checks the connection on the PB/SLP pin; if the resistance between the PB/SLP pin and ground is larger than 5.5MΩ, the device is configured as I2C programmable. Otherwise, the device is configured as resistor programmable.

When the MAX16163 powers up, it measures the resistance on the PB/SLP pin to the ground and sets the sleep time properly. It then asserts the OUT output. When the downstream device (e.g., a µC) finishes its task, it asserts a falling edge on the CLRB pin; the MAX16163 then deasserts OUT and the sleep timer starts. When the sleep timer expires, the MAX16163 asserts OUT again.

When the MAX16164 powers up, it measures the resistance on the PB/SLP pin to the ground and sets the sleep time properly. It then keeps OUT deasserted and puts the device in SHUTDOWN state. The MAX16164 does not assert OUT until a pushbutton closure on the PB/SLP pin.

The MAX16163/MAX16164 operate over the -40°C to +125°C temperature range and are available in a 1.54mm x 1.11mm, 6-bump thin wafer-level package (WLP) and a 6-pin µDFN package.
