LA-ispPAC-POWR1014/A Automotive Family:In-System Programmable Power Supply Supervisor,Reset Generator and Sequencing Controller Data Sheet
■Lattice's Power Manager II LA-ispPAC-POWR1014/A is a general-purpose power-supply monitor and sequence controller, incorporating both in-system programmable logic and in-system programmable analog functions implemented in non-volatile E2CMOS® technology. The LA-ispPAC-POWR1014/A device provides 10 independent analog input channels to monitor up to 10 power supply test points. Each of these input channels has two independently programmable comparators to sup-port both high/low and in-bounds/out-of-bounds (win-dow-compare) monitor functions. Four general-purpose digital inputs are also provided for miscellaneous control functions.
■The LA-ispPAC-POWR1014/A provides 14 open-drain digital outputs that can be used for controlling DC-DC converters, low-drop-out regulators (LDOs) and opto-couplers, as well as for supervisory and general-purpose logic interface functions. Two of these outputs (HVOUT1-HVOUT2) may be configured as high-voltage MOSFET drivers. In high-voltage mode these outputs can provide up to 8V for driving the gates of n-channel MOS-FETs so that they can be used as high-side power switches controlling the supplies with a programmable ramp rate for both ramp up and ramp down.
