Hi Sreehari,
Field recently moved to a different role in the company. I am not sure how he was intending to measure this timing for you since the EVM has different capacitance values. I think it may be better to use the transient simulation models here…
Part Number: LP8733 Tool/software: Our client has asked certain doubts regarding the PMIC which manages the system power flow. We are using AM2431BSDFHIALVR IC. 1. What is the default power up sequence for the LP87334DRHDR IC and is it advisable to go ahead…
Part Number: LP8733 Hi,
I have questions when VANA goes down below VANA_UVLO. I understand When VANA < VANA_UVLO, all power rails is shutdown without switching ramp and shutdown delays. How about GPO signals? What is behavior of GPO signals when VANA…
Part Number: TPS65219 Other Parts Discussed in Thread: AM2431 , LP8733 , , Hi Experts,
We are in a board design with AM2431 MCU along with LPDDR4 and 2 No.s of RGMII Ethernet. (Voltage rails are 0.85V, 1.1V, 1.8V, 2.5V & 3.3V).
I am planning to use a power…
Part Number: LP8733 Hello Expert,
For the below PMIC's we are looking for PGOOD de-assert timing when it senses fault.
1. LP873349RHDRQ1
2. LP875651RNFRQ1
3. LP87521FRNFRQ1
As per the datasheet PGOOD is configurable using OTP. Could you please help…
Part Number: LP8733 Other Parts Discussed in Thread: AM6412 , TPS745 Hi, My customer is using LP873364 for AM6412 power supply as it is recommended solution in below document. https://www.ti.com/jp/lit/an/slda059/slda059.pdf?ts=1690441858442&ref_url=https…
Part Number: LP8733 Hi,
My customer wants to simulate LP8733. We can find the LP873320Q1 Pspice transient Model, but they wants to use other derivative devices. Is it possible to use the Pspice model for other derivative devices? Please advise us.
Thanks…
Part Number: LP8733 Other Parts Discussed in Thread: AM2431 Use LP87334D for power supply for AM2431.
I refer to "Figure 5-7. Using LP87334D to Power AM243x (ALV Package) with LPDDR4 Memory Support" in ”Using LP8733xx and TPS65218xx PMICs to Power AM64x…
Part Number: LP8733 I intend to use LP87334DRHDR.
I will use BUCK0 (0.85V), BUCK1 (3.3V) and LDO0 (1.8V). I do not use LDO1 (1.8V). OTP defaults to LDO1_EN=high and EN_PGOOD_LDO1=yes.
1) On power-up, I expect the PGOOD pin to be Active High. Before accessing…
