5 / 14 page Tripath Technology, Inc. – Preliminary Technical Information 5 TPS4100 – KL/Rev. 2.5/02.05 TPS4100 Pinout PIN NAME/FUNCTION TYPE DESCRIPTION 1 SLEEPB INPUT (L) Logic input, ACTIVE LOW. Setting SLEEP to low puts the TPS4100 in sleep mode. Input range is 0 to 5V with 3.3V compliant inputs. 2, 4, 6, 8 Y1, Y2, Y3, Y4 INPUT (L) Non-inverted switching modulator inputs. 3, 5, 7, 9 Y1B, Y2B, Y3B, Y4B INPUT (L) Inverted switching modulator inputs. 10 MUTEB INPUT (L) Logic Input, ACTIVE LOW. Setting MUTE to low puts the device in mute mode. Typically driven by external power supply or microcontroller. Input range is 0 to 5V with 3.3V compliant inputs. 11 AM INPUT (L) Logic input, ACTIVE HIGH. Enables Analog Mode operation. Typically driven by Tripath controller. Input range is 0 to 5V with 3.3V compliant inputs. 12 5VGEN OUTPUT On chip 5V regulator bypass capacitor connection 12 HMUTEB OUTPUT (L) Logic output, ACTIVE LOW. HMUTEB low indicates TPS4100 is in mute mode 13, 14 AGND GND Analog ground 15 CPUMP OUTPUT Charge pump output capacitor 16 OUT4P OUTPUT Positive Output Channel 4 17 VPP4 POWER Positive Supply Voltage Channel 4 18 PGND GND Power Ground for Outputs 3 and 4 19 OUT4N OUTPUT Negative Output Channel 4 20 OUT3N OUTPUT Negative Output Channel 3 21 VPP3 POWER Positive Supply Voltage Channel 3 22 OUT3P OUTPUT Positive Output Channel 3 23 FAULT OUTPUT (L) Open Drain Logic Output, ACTIVE HIGH. FAULT high indicates fault condition. 24 OUT2P OUTPUT Positive Output Channel 2 25 VPP2 POWER Positive Supply Voltage Channel 2 26 OUT2N OUTPUT Negative Output Channel 2 27 OUT1N OUTPUT Negative Output Channel 1 28 PGND GND Power Ground for Outputs 1 and 2 29 VPP1 POWER Positive Supply Voltage Channel 1 30 OUT1P OUTPUT Positive Output Channel 1 31 DCAP OUTPUT Oscillator output for driving external charge pump circuit 32 PGND GND Power Ground |
