Patrick J. Hibbs - Murphy TX, US
Assignee:
Tyco Electronics Corporation - Berwyn PA
International Classification:
H02M 7/06
US Classification:
363126
Abstract:
A controller circuit for activating and deactivating an electrical power converter that provides power to a device includes power input terminals on a primary side, and power output terminals on a secondary side, which are configured to provide power to the device. The controller circuit includes a detection circuit configured to determine whether the device is connected and, if connected, causes power to be routed to the electrical power converter to activate the electrical power converter. When the device is not detected, the electrical power converter is deactivated until the device is reconnected.

US Patent:
20190131039, May 2, 2019
Filed:
Nov 2, 2017
Appl. No.:
15/801689
Inventors:
- Chicago IL, US
Kedar Bhatawadekar - Santa Clara CA, US
Dong Yu - Fremont CA, US
Assignee:
Littelfuse, Inc. - Chicago IL
International Classification:
H01C 17/00
H01C 7/02
H01C 7/13
H01C 1/14
H01C 17/28
Abstract:
A method of forming a positive temperature coefficient (PTC) device, the method including providing a core formed of a PTC material, the core having an electrode disposed on a first surface thereof and a second electrode disposed on a second surface thereof, connecting a first lead element to the first electrode, applying an oxygen barrier epoxy to at least portions of the core, the first electrode, the second electrode, and the first lead element, and curing the oxygen barrier epoxy to form an oxygen barrier package surrounding at least portions of the core, the first electrode, the second electrode, and the first lead element.

Electrical Circuit Protection Device With High Resistive Bypass Material

View page
US Patent:
20180366293, Dec 20, 2018
Filed:
Jun 16, 2017
Appl. No.:
15/625191
Inventors:
- Chicago IL, US
Kedar Bhatawadekar - Santa Clara CA, US
Dong Yu - Fremont CA, US
Assignee:
Littelfuse, Inc. - Chicago IL
International Classification:
H01H 85/055
H01H 85/048
H01H 85/165
H01H 85/02
H01H 85/143
H01H 85/20
Abstract:
A fuse suitable for arc quenching is disclosed. The fuse incorporates a high-resistive material or element placed in parallel relationship with the fusible element to mitigate, minimize and/or prevent arcing during an overcurrent condition. By incorporating a high-resistive material or element in parallel with a fusible element an alternate or second path for current flow during an overcurrent condition is provided. As such, during normal operating conditions, current travels through the fusible element. However, during an overcurrent condition, the resistance through the fusible element increases. Once the resistance through the fusible element is greater than the resistance through the high-resistive material or element, the current will bypass the fusible element and travel through the high-resistive material or element. In this manner, arcing through the fusible element during the overcurrent condition can be prevented or minimized.
