M-BUS Design Changes
Between TSS721A and
NCN5150
NCN5150 is a drop in replacement of the TSS721A for all designs
using a VDD capacitor larger than 1 mF. The NCN5150 M−BUS
transceiver (in SOIC version) is pin−to−pin compatible with the
TSS721A from Texas Instruments™ and can replace this component
with no changes to the PCB layout on a typical implementation. Some
minor differences between both parts are detailed in this document.
Summary of Differences
• No transistor required on STC for fast start−up
• Minimum required decoupling capacitance on VDD
External PMOS Transistor on STC
The TSS721A requires an external PMOS transistor (BSS84) in
series with the STC capacitor if this capacitor is larger than 50 mF in
order to meet the maximum start−up time requirement by the M−BUS
standard. The NCN5150 does not require this transistor (QSTC), and
allows the STC capacitor to be connected directly to the STC pin.
Optionally, for existing PCB layouts where no possibility exists to
bypass the transistor footprint, the transistor can be kept in place
without any problem.
VDD Decoupling Capacitor
The NCN5150 requires a minimum total decoupling capacitance
(CVDD) of 1 mF on the output of the 3.3 V regulator to remain stable.
Typical designs with the TSS721A will use a 100 nF capacitor.
