Part Number: TPS3801 In the datasheet SLV219E Oct. 2010 of TPS3801K33DCKR there is a statement on Power-up reset voltage(2) and corresponding foot note says: “(2) The lowest supply voltage at which RESET becomes active. tr, VDD ≥ 15 us/V.”…
Other Parts Discussed in Thread: TPS3801 Hi
Colud you tell me the thermal resistance θJA and FET's on resistance in RESET port of TPS3801-01DCKR?
Best regards,
Mitsuo
Other Parts Discussed in Thread: TPS3801 Hello,
With the TPS3801 series supervisors, how can I achieve a guaranteed reset at 0V?
Nearly every competitor supports this specification with the addition of a 100K pull-down to GND (assumes input leakage current…
Question/Problem:
Does hysteresis vary with trip voltage
Answer:
Yes. Datasheet provides specific typical numbers that show this variation with trip voltage.

Hello guys, i'm trying my first class-D amplifier for a 5.1 audio system.
My doubt is about the voltage range of the analog inputs of the IC (as using single-ended inputs). In datasheet…
Patrick,
We make no difference between TA and Tj so all ratings that mention TA apply for Tj as well. This applies to operating temperature range as well. Please refer to the note under the ABS MAX table in this similar device: www.ti.com/.../tps3801…
Ben,
We don't offer the 4.00 variant of this device anymore, and the only 4.0 non-adjustable supervisors we carry are the LP3470 and the TPS3801. The most similar to the LM809 is the LP3470 but the price isn't in the same ballpark. Please contact me…
Hi Den,
For the LDO, please consider TPS783. The reason you may like this part over other devices is the low Ignd of the TPS783. You can find the parametric search optimized for Ignd here .
For the detector/supervisor, please consider LP3470. This has…
There is no user method for setting the battery cut off voltage. You might consider adding a series PFET between the BAT pin and GND, with its gate driven by a SVS (comparator+reference) like TPS3801-01 or similar.
