Part Number:TPS2595
I am using the TPS259573 as a BPS according the to the reference design in the following application note (Figure 14). When connected to a power supply or a battery, the battery side switch consumes around 25mA at 16V in shutdown state, the consumption is not immediate though, it increases exponentially 20 seconds after the battery is connected, the voltage at CdVdt also ramps up simultaneously. This power dissipation is only observed in the battery side switch (also confirmed with a thermal camera) when both switches are off.
The two switches are kept off with a voltage divider and are enabled by pulling the !EN!/OVLO pin low.
R1= 1M ohm
R2= 470k ohm
R I lim1 = 1.3k ohm
R l limi2 = 470 ohm
CdVdt = 4.7nF
