Frequently Asked Questions
What is the LM3881MM and what does it do?
The LM3881MM is a single-channel power supply sequencer IC from Texas Instruments, housed in an 8-VSSOP package. It monitors and controls the sequencing of power supply rails, ensuring that voltage domains power up and power down in a defined order to protect sensitive components such as FPGAs and processors.
What package does the LM3881MM come in, and what are its dimensions?
The LM3881MM is available in an 8-pin VSSOP package (JESD-30 code: S-PDSO-G8), equivalent to TSSOP8 with a 0.19-inch body width. This compact surface-mount package is ideal for space-constrained PCB designs in consumer and industrial electronics.
What are typical applications for the LM3881MM?
Typical applications include power sequencing in FPGA and DSP boards, multi-rail power management in servers and telecom equipment, and industrial control systems where specific power-up sequences are required to prevent device damage or data corruption across multiple voltage domains.
Can the LM3881MM be cascaded for multi-channel sequencing?
Yes. Although the LM3881MM provides one sequencing channel per device, multiple units can be cascaded to manage complex multi-rail sequencing requirements. This makes it flexible for systems with three or more power rails that need precise power-on and power-off ordering.
Where can I buy the LM3881MM and what is the price?
The LM3881MM is available from authorized distributors worldwide, including Mouser, Digi-Key, and other global electronics suppliers. The price starts from approximately $3.44 per unit, with pricing varying based on order quantity and distributor. FindMyChip also offers worldwide sourcing with fast shipping.
