PEB2026T-S

The PEB2026T-S is a kind of IHPC (ISDN High Voltage Power Controller). It is designed for feeding two-wire ISDN-transmission lines. One line can be powered by one IHPC. 

There is some information about the features: (1)battery voltage up to 130 V; (2)supplies power for one transmission line; (3)current limiting and chip temperature control; (4)limiting current can be programmed by an external resistor; (5)automatically reduced feeding current in case of overtemperature; (6)reliable 170 V smart power technology ; (7)small P-DSO-20 package.

The following is about the absolute maximum ratings: (1)VBAT (Battery voltage referred to GNDB): -150 to 0.5 V; (2)VDD (VDD  supply voltage referred to GNDD): -0.5 to 6 V; (3)VREF (voltages on REF referred to GNDD): -0.3 to VDD + 0.3 V; (4)VCP (voltages on CP referred to GNDD): -0.3 to VDD + 0.3 V; (5)VCN (voltages on CN referred to GNDD): -0.3 to VDD + 0.3 V; (6)VCTP (voltages on CTP referred to GNDD): -0.3 to VDD + 0.3 V; (7)VAPFI (voltages on logic output APFI referred to GNDD): -0.3 to VDD + 0.3 V; (8)VRB (RB voltage referred to GNDB): -0.5 to +0.5 V; (9)IRB_peak (RB peak current): -16 to 16 A; (10)Tj (junction temperature): 150.
